This is a tolerance test design in Fusion 360 for my Cherry MX keycap generator CAD designs:

This design uses the following base dimensions for the + shaped switch stem from Cherry MX official drawings:
Width: 4.1mm
Thickness: 1.17mm

The final width and thickness of the stem hole is calculated with a parameter called MXHoleTolerance which widens the stem hole in the keycap slightly.

Instructions:
1. Print a range of test pieces with varying tolerances. For SLA printers, around 0.05mm seems to work well, for FDM printers maybe over to 0.1
2. Try inserting them onto your mechanical switches and find the one with the best fit
3. Open the Keycap generator (links above), go into MODIFY -> Change Parameters and change MXHoleTolerance to the value listed on the print with the best fit
4. Use the keycap generator to create and print the keys of your dreams

Note: even FDM printers only have a
