Rack Ends: Current design

Added on by Spencer Wright.

I'll be writing more about how I'm going about procuring my stainless steel rack ends later, but I wanted to give an idea of the sorts of design files one needs to supply machine shops with in order to get quotes. A dimensioned (and toleranced!) PDF is always key:

N.B., my drawing template is pretty lame right now. Not having standard tolerances listed is a total no-no, but most manufacturers assume +/- .005" on any distance and +/- 1 degree angular - so I should be okay. I really just need to spend a morning setting up a new template, but that's fairly low on my priority list right now. Anyway... do as I say, not as I do.

I also usually include a STP file, but as a rule that's *only* for reference. I suppose that if you had a particularly strong relationship with a supplier and were sourcing a part with *only* standard tolerances, skipping the PDF would be okay... but that's a rare scenario.

Aaaand, thanks to my friends on Twitter, you can see the part in 3D here:
