this is a cherry MX switch with very low precision. done in a few minutes to use as illustration/gross reference in other projects.
I based most on measuring with a caliper on some old switches i have. and on references from geekhack. Here is a much better model (but using the lame sketchup format)
The only measurements that i double check everywhere i could are the ones required to: 1) attach a keycap; and 2) attach the switch to a plate.
