Manufacturing guy-at-large.

On Makerism

Added on by Spencer Wright.

A few weeks ago, a reporter reached out to Zach and I to say that he was including us in a list of Brooklyn makers to know. He had a question as well:  How do you define "maker"?

This isn't something I've thought about in a while, and to be honest I've never really considered myself a maker in the first place. So while I was flattered to be on someone's top ten list, my response was nuanced: 

More than anything else, I think "maker" is a cultural signifier - something that denotes a certain sense of whimsy, combined with a bit of precociousness and craft. In the best cases, makerism is simply a gateway to something else; it's a stepping stone that eventually leads to a product business or a manufacturing operation. Zach and I have put a *lot* of energy into making this transition over the past few years, and most of the other people on your list have as well.

To be a bit more blunt: I've actively eschewed makerism in my own work. Not that I don't do makery projects or like cute things. But my tolerance for whimsy is relatively low, and the things that get me excited are real, sustainable businesses, and ultimately I find it difficult to maintain a strong sense of playfulness while my primary focus is on building something.

I'm sure other people have other definitions of what it means to be a maker, and those are perfectly valid. But I'd encourage everyone, as they're working on something new, to consider whether they're actually a maker - or if they're really just building a business around a cute product.

Now, to work

Added on by Spencer Wright.

In reality we've been chugging away nights & weekends for months, but it's nice to have it be official:

As I said on The Prepared's podcast a few weeks ago, it's still a bit crazy to me that people like this thing that we came up with. It's fun - a rare way for me to relate to people who are otherwise totally dissimilar to me. 

There'll be lots to share over the next few months, and I look forward to sharing it. Thanks *so* much to everyone who kicked in - we're really excited to have you with us!

The Prepared's podcast + A history of The Public Radio

Added on by Spencer Wright.

Some updates!

So, I've been working on some stuff. 

First: Thanks to The Prepared's *awesome* donors, I've redesigned and relaunched Awesome!

Second: In the spirit of expanding The Prepared's purview (which is why I'm taking donations in the first place), we now have a podcast! The goal of it, as with this newsletter, is to help people prepare for good work - and to share the results of the big things they've worked on. To kick things off, we've got two episodes: One with Zach on the history and future of Centerline Labs, the company we cofounded to create The Public Radio, and one with Zach and Gabe about some of the things we're thinking about on the eve of...

ThirdThe Public Radio's launch on Kickstarter! I'm very excited about this, and it deserves a bit of explanation:

The Public Radio started in 2013 as a longshot side project - "a product idea for a single-band FM radio," as I described it four years ago. Going back through my blog while filtering for the "publicradio" tag shows a funny story. Early on, I posted a lot of "this was my workday" posts. Then there was more topical content - my struggles finding the right potentiometer; little thoughts on how to take crowdfunding offline. In early 2014 Adafruit posted something short about us, and shortly after we soft launched

All of that was under looks-like prototypes; it wasn't until mid 2014 that we had a works-like, which we assembled (without SMT stencils! we were so naive) by hand. At this point the design iterations were more substantial, but it wasn't until late that year - after our first Kickstarter campaign - that things really became serious.

At this point we started getting some real attention, and a bit of backlash as well. It's worth mentioning that at the time, my days were spent consulting for Bank of America and GE on management & marketing strategy; The Public Radio was a weird thing to match that with. But it was getting *fun* - real engineering problems, real supply chain problems; real business problems; real press coverage; my first injection molded part. I was interviewed by New Hampshire Public Radio and by Matthew Lesko, the guy who wears the question mark suit on old '80s infomercials. 

And then, all of the sudden, we (with the oh-so-gracious help of friends/family/indentured servants) shipped 2500 radios to people all over the world. We missed our Kickstarter shipping goals by about a week; pretty good.

Almost immediately afterwards, we went to China to plan for v2.0. We visited our speaker supplier in Dongguan and roamed the Shenzhen electronics markets, and did all of the other things you'd expect. But as we were heading back to the US, my day job was in the process of vaporizing, and for the ensuing two years The Public Radio has largely been relegated to the odd warranty email.

So, this relaunch. The thing is, The Public Radio is a good product, and we want to find a way for it to live on. This is harder than it sounds. No matter how much the traditional supply chains are being (*cough*) disrupted, it's still really hard to run a hardware business in your spare time. The Public Radio is an incredibly simple device - intentionally so - and yet it's real work to get it made.

But we're trying anyway. We've got a pretty nice plan here - one that keeps TPR lean on capital requirements, keeps our supply chain short, and (most importantly) makes for a really nice customer experience. There's a lot to unpack here, and you can bet that I'll be sharing more here in the next few months :)

Anyway, that's that. Please, check out The Public Radio on Kickstarter and share it!!!! They look great, work great, and make for *excellent* gifts. And as we build out our manufacturing process, you'll be right there learning about it with us!

Desk right now

Added on by Spencer Wright.

A brief calm between many storms: 


I've spent a lot of time here over the past few months. Much of my work at nTopology  happens here; probably half of The Prepared's management and composition; a *lot* of reengineering & planning for The Public Radio. Plus the odd proverbial cat video, etc. 

I'm very lucky to have such a great work space; I'm looking forward to the next few (hectic) months.

The Prepared's Podcast

Added on by Spencer Wright.

As I've said here before, The Prepared was never meant to be a media operation. And yet, when I think of its place in my life and in (apparently) the lives of its readers, it's just that - and I can't help but want it to be more

So I'm happy, then, to announce The Prepared's first experiment into audio. Appropriately enough, the first episode of The Prepared (the podcast) is a conversation between myself and Zach Dunham, the better half of The Public Radio - which, as it happens, is *about* to relaunch on Kickstarter.

You can subscribe to The Prepared's podcast on iTunes or on my favorite posting app, Overcast. Heck yeah!

Stem prints

Added on by Spencer Wright.

Almost a year ago, I posted a rendering of my printed bike stem on my blog here. Now:

These parts were printed by my friends at Playground Global on their 3D Systems DMP320 in titanium 6/4. Like the titanium parts I've had printed (and written about extensively) in the past, these are done via laser metal powder bed fusion - the generic name that often gets referred to as "DMLS". These parts were, of course, designed in nTopology Element Pro; you can see more of my design process here

As loyal readers will know, I've put a lot of time into using Abaqus to predict these parts' mechanical properties; more on that in the near future. For the time being, the goal with this print was to test the manufacturing process - and use any lessons here to guide future design iterations. As you'd imagine, there's a *lot* that goes into printing a part that has ~45,000 beams; establishing manufacturing parameters was a good way to filter out nonviable design strategies.

It'll take a bit more work to characterize the as-built design fully, but at first inspection it seems to have been a total success. I was careful to keep most of the beams' orientations at a high angles, thicknesses above .45 mm, and lengths below 3 mm; the result is a structure that's almost completely self supporting.

At this point, the part has been roughly cleaned up and bead blasted to remove any surface discoloration. The next step is to tap the holes, clean up the clamp surfaces, and mock the entire assembly up.

More soon :)

See also: DMLS lattice sample prints, where I describe the part's design a bit more.

Stamping die changes

Added on by Spencer Wright.

So, Zach and I have been working on an updated version of The Public Radio, and I figure we're about due for a manufacturing update. So! Here goes:

This is the same progressive stamping die I've shown here, but with some small changes. The locations and diameters of our main assembly screws have changed, and as a result the tool needed to be modified. 

The cool thing about progressive stamping is that you have multiple stations - in this case five - to work with. As seen above, the stations go right to left. Initially the screw holes were punched in station one (far right), but now they're being done in station two. Making this change just requires removing four punches and then adding four new ones + corresponding holes; the old holes are simply left unused.

We've got a few other updates coming up, including visits to a few factories and a new assembly/tuning management process. Stay tuned :)

NYC and Cultural Import

Added on by Spencer Wright.

A recent episode of The Riff, a podcast I've been enjoying recently, centered around a conversation about New York City's cultural influence. In it, Andy Weissman (a lifetime New Yorker whose perspectives I've grown to enjoy on Twitter) proposes the following:

My theory is that right now New York is at a peak and is on the downside of its political, economic, cultural, and social import.

This makes me concerned both as a New Yorker and as someone who likes when old things maintain their relevance. Interested people should check out the full conversation; both David Tisch and Pam Wasserstein makes some good points about New York's cultural diversity, and the whole episode is both challenging and fun. I also have a (possibly hopeful) feeling that Andy is just trying to stir up shit & get other people excited about doing great work in NYC, but that's beside the point. The question, to me, is this:

Assuming Andy's theory is correct, what do we as New Yorkers do about it?

My thoughts:

  • Work on stuff that has existential import. My main beef with Andy's argument is that he repeatedly uses Snap (née Snapchat) as the prime example for why LA is beating NYC right now. And while I will readily admit that media distribution & communications is a great business to be in if you want people to care about you, I can't help but think that in the next century, the global cultural impacts of Tesla and SpaceX will be both more powerful and more inspirational. NYC used to take on projects of this scale, but our output of late has been more focused on things like... wearables. If we can lead in exporting technologies that address existential problems, I think the whole world will be better off.
  • Embrace our own populism. To most of the world, NYC's image has a great balance of populism (it's still a *huge* magnet for immigration) and aspiration (everyone knows that wealthy people live here). But I worry that to rural American audiences, NYC seems cold, elitist, and out of touch - when to me, NYC is the warmest and most inclusive place on earth. Obviously this has political consequences, but my main concern is that NYC remains a magnet for the most talented people in the US - and it's hard to do that if people think you don't like them.
  • I believe that successful cities depend on high functioning infrastructure, and we badly need to find new ways to upgrade ours at lower cost. David Tisch makes this point in the podcast, and it's something that I've thought about more and more recently. We may have the best public transit in the country (I certainly think we do) but we're far behind other cities in the world. Unless we come up with new ways to get new subways built and old ones upgraded, it feels like we'll have a hard time competing on a global scale.

In a nutshell: NYC needs to work on meaningful stuff, maintain an approachable image, and figure out how to improve its basic urban operations.

If this is something you're working on, let's talk.

Changing the world around us

Added on by Spencer Wright.

Every few weeks, someone asks me what I think the future of 3D printing is - whether it's going to really change the way things are made.  My response is to ask if the name "PCC" means anything to them - a question that almost always elicits a blank stare.

PCC is a manufacturer of castings and forgings, primarily for aerospace and power generation. They live mostly outside of the public eye; to most folks, casting pretty much begins and ends with old-school iron cookware, and few stop to consider how improvements in casting techniques might have changed the cost and availability of electricity and air travel over the past half century.

And yet they have had a big impact. PCC sells about $10B worth of products every year, supplying critical propulsion and airframe components to companies like Boeing and Airbus. Many of these parts allow airplanes to reduce weight and improve engine efficiency, helping along significant improvements in fuel economy per seat. And so, in 2016, Precision Castparts Corp was acquired by Berkshire Hathaway for $37.2B. It's the largest amount that Warren Buffett has ever spent on an acquisition. 

I bring this up to say: The tech press may maintain their interest in 3D printing, or they may not. It's possible that, in a few years, I'll walk into a retail shop and have made-to-fit parts printed for me on demand. It's possible that manufacturing will become distributed; that supply chains will spin up and down at a moment's notice; that computers will engineer products from start to finish.

But there are many other, less sexy ways to change the world around us. And we'd all be well off if some 3D printing method achieved one of those instead.

Standards Orgs

Added on by Spencer Wright.

This week, I participated in ASME's Technology Advisory Panel on Additive Manufacturing. This is the third standards body that I've gotten involved with in the past year or so (I also sit on ASTM F42, and represent nTopology at the 3MF Consortium), and I wanted to post a few thoughts about standards development for anyone who's curious about them or interested in being involved in similar work.

  • Most standards bodies were formed out of some deep-seeded industry need: A spate of high profile product failures, a growing sense of frustration amongst customers, etc. Standards are the industry's way of improving their overall product quality, or their public image, or their relationship with key customers (the US military especially).
  • Standards orgs make money partly by selling standards and partly by enforcing them and certifying products/companies that comply. As an independent product developer, that can be frustrating (I wrote about this years ago); spending a few hundred dollars to find out how your part will be tested can often seem like a shitty alternative to more... open approaches. On the other hand, most standards orgs are all-volunteer and nonprofit. 
  • The fun thing about standards development is that if you care, they'll (for the most part) take you seriously. It doesn't particularly matter if you're officially "in the industry," and you certainly don't need to work at a huge company or have any specific set of interests in the matter at hand. When I joined F42 (ASTM's subcommittee on additive manufacturing), I was working at a consultancy whose primary clients were in marketing and HR. I was working on AM in my free time, and like any intelligent person had developed thoughts on issues the industry was facing; ASTM took me in like any other.
  • As something of an outsider myself (in a strict sense, I am not an engineer per se), the experience of being on a more or less level playing field with folks who have spent their careers at global engineering & manufacturing companies is really something. I get a lot out of hearing their takes on the industry, and am glad that someone (me) is there to provide the perspective of a generalist working across disciplines. Standards orgs tend to be places with a high degree of empathy, and it's a pleasure to talk openly - from competitor to competitor, supplier to customer - about how to push an industry in a better direction.

Only the last 10%

Added on by Spencer Wright.

From a conversation on engineering between Arup's Dan Hill and Tristam Carfrae:

In response to fears that this kind of 'algorithmic architecture' will marginalise engineers and architects, Carfrae states that this kind of approach is only really "optimising the last 10% of a problem." The software has to be described and tuned with a particular strategy or problem in mind, and that comes from the designer, not the software. 

The point here is one that I've argued many times in the past: Today's optimization approaches (and any in the adjacent possible future) do not, in fact, put computers in the driver's seat of engineering or design. Instead, they use computers to automate rote tasks that an engineer is interested in exploring.

I believe this distinction is critical, as it affects both the direction of CAD companies' efforts and the enthusiasm of a new generation of engineers. It's my desire to see the CAD industry prioritize efforts that'll have big, positive impacts on the world, and it's my goal to keep smart, driven people from becoming disillusioned with engineering. As a result, I'd encourage marketers, journalists and onlookers to seriously consider what they believe about optimization, and to be wary of anyone who tries to sell them an AI enabled Brooklyn Bridge.

For more background on optimization and the future of CAD software, see Displaced in space or time, The problem with 3D design optimization today, Computer aided design, and Exploration and explanation.

Fostering the conditions

Added on by Spencer Wright.

From a recent Stratechery article on Amazon & Alexa:

You don’t make good products because you really want to, you make good products by fostering the conditions in which great products can be made.

This is something I've put a lot of thought into, starting around mid 2012. At the time I was leading development of a highly complex electromechanical system (robot doors), a process which was itself embedded into pretty much the most complicated residential construction project you can imagine. The engineering tasks we faced were formidable, and the schedule was extremely tight - but in many ways the cultural aspects of the job had an even bigger impact on what we built.

Since that experience - and urged along by my time at Undercurrent and my work studying product companies like McMaster-Carr and Amazon - I've only become more convinced of how critical it is to foster the kind of engineering, product, and project cultures that are appropriate for what you're building. 

Build what's right for the team that you are; Be the right team for what you want to build. 

My ideal, practical, engineer's desk

Added on by Spencer Wright.

Note: I'm considering making a small run of these desks available for sale. If you're interested, let me know!

Last week I finished assembling the new desk I've been working. It's been a big upgrade to my home office, and I'm really happy with how it turned out. 

To recap:

The goal was to create a functional workstation that could be assembled (and disassembled) easily. It should have a distinctive aesthetic, use durable materials, and be sturdy as all get out. Its primary use will be as a computer terminal; but as it's designed for engineering work it'll also serve as a de facto hub for parts inspection, reverse engineering, and the occasional wrenching. 

Initially, I had wanted to get a slab of live edge walnut and make something classic. But after some consideration I realized that wasn't really appropriate. Wood's fantastic, but it offers zero modularity (making the desk difficult to move - bad for expanding workshops) and is rather messy to work with (bad for making changes down the line). In addition, the aesthetic of live edge desks tends towards cast iron and welded steel: beautiful materials in their own right, but not ones that are convenient for me to work on.

Unidirectionally wound carbon fiber tubing is subtle, but when it catches the light it looks *great.*

So: Carbon fiber legs. I've worked with composites since my bike days, and found that it offers some nice benefits over metalwork. Carbon tubing is light (not critical when you're using the desk, but sure is nice for shipping/moving), stiff, aesthetically distinctive, and easy to cut to length. 

To finish the legs' structure, I used 3D printed resin nodes. I wanted something that had good surface finish and high tensile strength, and I wanted good elongation so that nothing would break if I *really* hammered on something on the desk. Formlabs came through on all counts; their Tough resin performed fantastically. 

Formlabs' Tough resin (which I painted a matte black) make excellent connection points for the desk's structure.

Next, I needed a suitable surface to work on. After researching a variety of composite surfaces, I settled on phenolic resin. It's impervious to all sorts of harsh chemicals (including coffee cup rings), is cost effective, and has a nice monolithic feel that laminates just don't. It's also easy to machine and adhere to, which came in handy when attaching the subframe.

In order to reduce deflection in the work surface - and to allow for continuous attachment points under and on the sides of the desk - I designed an 80/20 aluminum extrusion subframe. Aluminum extrusions are fantastic for this kind of thing; they're light, strong, and easy to fasten to. And 80/20's selection of brackets and attachment options allow me to add accessories and even reconfigure the desk down the road. I attached the subframe with two machine screws and two strips of VHB tape.

Right off the bat, I knew I wanted three accessories attached to my desk:

  • A two-arm monitor stand outfitted with a laptop tray. I swap back and forth between a MacBook and a CAD laptop, and this setup has proven *really* convenient.
  • A serious, 12 outlet power strip. This mounts directly to the 80/20 subframe, and offers plenty of fixed and flex space for whatever I need to plug in.
  • Hooks for hanging my briefcase & camera bag. I mounted these to 80/20's sliding hangers using stainless steel twist shackles - an excellent setup.

Since finishing the desk, I've settled into it nicely. I love the feel of the phenolic, and *really* appreciate how stable the whole setup is. I'm continuing to play with my exact layout - my home office is a bit in flux - but having this as a new centerpiece makes me feel much more grounded.

A big thanks to Formlabs for helping out with the node engineering & printing - and for sharing a complete guide on painting SLA parts! 

Desk fab

Added on by Spencer Wright.

This weekend, in addition to setting up an Abaqus beam sizing optimization on my lattice bike stem, I got about 80% of the remaining work on my new desk done. Completing it (which I should get done in the next week) will be a long awaited upgrade to my home office, and I've put a lot of research and care into selecting my materials and designing a system that's functional, lightweight, aesthetically pleasing, and modular. The structure is based on unidirectionally would carbon fiber tubing - the same stuff that I use for my titanium-carbon road bike seatpost

I cut the tubing to length with a 10" diamond grit blade, and use a piece of aluminum oxide wet/dry cloth to knock down any slag (stray, partially cut fibers). I then wiped the tubes down with tack cloth and used a two-part high gloss clear coat to seal and protect the tubes. The result looks great - it's hard, smooth, and allows the fiber to shimmer when it catches the light. 

The last pieces to prep before assembly are the frame's nodes. These were printed on a Form 2 in their "Tough" resin, which most people would use for functional prototyping but which I'm planning to use indefinitely. I considered leaving the nodes in their natural blue-green (you'll note that I even changed the color on the parts in my model a few months ago), but ended up deciding to paint them black. 

I was a bit hesitant to take on a finish paint job - I've been painting more and more recently, but my spray skills are mostly untested on small, intricate parts - but Formlabs has a good two part (one, two) guide and anyway I didn't have any other options. I used the Tamiya primer and spray paint they suggested (a note on this: Tamiya's bottles are pretty small. I ended up buying three bottles of primer and five bottles each of black topcoat and matte clear.), which goes on soft and easy - much nicer than the big rattle cans that I'm used to.

I've still got to sand, prime and paint three more of the nodes, but once that's done I'll be able to assemble the entire desk and start attaching accessories - which, because I'm particular about my workspace, will be more complicated than maybe most people's setups :) 

More soon!

Snapshots of a day

Added on by Spencer Wright.

Some semi-random screenshots from a day's worth of lattice design in nTopology Element Pro:

There have been a bunch of big updates to Element recently, and this workflow takes advantage of a few of them. In particular, the new Warp to Shape tool is very helpful; I also used the Extract tool and the Remesher to make some nice selective surface lattices.

The last, and really the biggest, thing here is the conversion into Abaqus for beam analysis & sizing optimization - see the last photo above. I'll be working on & posting more about that in the next few days - stay tuned :)

An ode to VHB tape

Added on by Spencer Wright.

I mentioned VHB tape in a post a few weeks ago, and last week a friend, who had read it, looked at me quizzically and asked "what's up with VHB tape?"

The thing is, VHB tape is awesome. It's an industrial strength, double-sided foam adhesive, capable of creating *really* strong bonds between basically anything that you'd want to stick together. I've used it in a few contexts, and encourage anyone who takes hardware projects seriously to keep VHB tape in mind as an alternative to welding, bolting, or gluing parts together.

I first became aware of VHB tape when building bikes, and used it (as part of 3M's "mushroom head" tape, which is the same stuff that EZPass uses to stick sensors to your windshield) to create a modular front rack system that didn't require bungee cords. Later, when I was working on robot doors, I seriously considered using VHB tape to bond mahogany cladding to the doors' aluminum frames; we eventually decided on structural adhesives, and dealt with a slew of issues resulting from differences in thermal expansion rates.

Most recently, I'm using a small amount of VHB tape to adhere the 8020 subframe to the phenolic resin top of my desk. I chose a thin tape - 1/2" wide and .020" thick - and am using it on the short ends of the desktop as a secondary fastening method (the primary connections are two M5 bolts). I'm using it here for a few reasons, which highlight VHB's advantages:

  • It's really strong. Not as strong as a structural adhesive like DP420 (with its overlap shear strength of about 4500 PSI), but for applications like the ones above, VHB's ~100 PSI dynamic tensile and 1000 PSI static shear strengths are *well* within my design objectives. 
  • It's really easy to apply. In most cases, isopropyl alcohol is all I've needed to prep the surface, and it's kind of nice to not have to manually mix up epoxy or get out a mixing gun. 
  • It stretches to accommodate differences in CTE. In this way, VHB is *much* better than rivets or nuts/bolts, and has big advantages over structural adhesives as well. According to 3M, VHB tapes can be stretched up to 50% of their thickness, making them ideal for applications where dissimilar materials need to be bonded, or where some shock absorption & vibration dampening is desired.
  • It has a predictable thickness. Glue is great, but planning for a consistent glueline can be tricky. VHB is available in a variety of thicknesses, allowing you to design the assembly just the way you want it.
  • It's relatively easy to remove. Disassembling a glue joint can be a major pain in the ass, but VHB is just acrylic foam; if you can fit a knife into the joint, you can usually cut the tape in half and pull the assembly apart. 
  • It's easy to keep in stock. Glue is great, but inevitably I end up with a hardened tube laying around, or run out of mixing nozzles right when I need them. VHB doesn't need any supporting equipment, and is shelf stable for two years - whether or not you've opened the package. 

Don't get me wrong - I keep a big selection of bolts on hand, and usually have a active tubes of cyanoacrylate, Titebond, and DP420 on hand. But my shop is much better for having VHB in stock, and my desk is much better off for having used it :)

Recent lessons, pt. 2

Added on by Spencer Wright.

More lessons from the past few years and beyond - these more personal than my previous post. 

  1. Few things feel better than getting consistent exercise, but few things feel worse than being told that you should be getting more exercise.  
  2.  There's nothing more fulfilling than setting someone else up to do what they love. Corollary: few things hurt more than to be denied the chance to do something that you're great at. 
  3. People will hate you for saying that having a baby is like having a dog - and for sure, there are significant differences - but that doesn't change the fact that it's true.
  4. Unless you have access to an actual soda fountain, you should add the ice cream to the root beer and NOT the other way around. 
  5. The ability to give advice well is a direct outgrowth of understanding and judgement; the ability to receive advice well is a direct outgrowth of humility and a sense of politics.

Desktop fabrication/assembly

Added on by Spencer Wright.

In between bouncing Nora around the past few weeks, I've been able to sneak in a little work on my new desk. I now have both the desktop (a 30" x 60" x 1" phenolic resin surface from JHC Lab Resin) and its subframe (a 20 mm x 40 mm extrusion frame from 8020), and have partially assembled them to each other:

The subframe only attaches mechanically to the desktop in two places - one bolt in the middle of each of the long frame legs. I *think* I'm also going to use VHB tape between the frame and the desktop, but I'm holding off on that until I get a few more of the parts in & prepped.

I also received the shelf (which is 12" x 48" x 3/4") and all of the carbon fiber tubing. I'll be cutting the tubing to length with a diamond grit saw blade, and need to drill & tap a bunch of holes in the shelf still as well. I'm also planning on mounting my old Wilton Bullet vise to the desktop using some nut inserts, but I'll probably hold off on drilling more holes in the desktop until I get the whole thing together and use it for a few days.

I should be getting the printed parts back from Formlabs in the next week or so, and because of the way it assembles I should be able to get the desk put together really quickly once they arrive. Fun :)
