Modular mechanical keyboard stand

Modular version of the keyboard stand to suit different keyboard sizes. I found the original to suit 60% and 65% keyboards well, but not longer or shorter sizes.

Print one of each piece, but pick the middle piece depending on your keyboard size:
Size A - 40% keyboards
Size B - 60 and 65% keyboards
Size C - 75% keyboards
Size D - 1800 and Alice style keyboards
Size E - full-size keyboards

The lengths were based on Akko/Ducky keyboards of standard sizes. There's a whole lot of non-standard keyboard layouts however, so compare to the reference lengths below to see which length might best suit your keyboard:
40%: ~292 mm
60%: ~316 mm
75%: ~365 mm
1800, Alice: ~380 mm
Full size: ~440 mm

Note:
- The pieces are intentionally designed with tight tolerances to keep them together without adhesives or fasteners. They should snap together with a satisfying click
