MX Switch stem holder

A bigger version of https://www.thingiverse.com/thing:4761144 drawn from scratch.

I liked the compliant mechanism functionality of that model, but it was way too small for me. So I drew it from scratch in Fusion using tominabox1's model as a reference point. The overrall dimensions are similar but not identical.

The "claw" cutouts that grip the stem might need some filing after printing.

UPDATE: 30.5.2021:

Made the stem claw cutouts wider, so the stem base sits flush with the holder, improving grip and stability. Enjoy !

UPDATE: 18.11.2021:

Added another model that has small sacrificial supports on the corners. Print without support, and just snap it off with pliers ! Helps with the problem of corners being curled up during printing.

You can increase the grip strength of the holder by increasing wall count.

Post-Printing

If the claws dont grip a stem smoothly, file or run an exacto knife through the cutouts to get rid of any extra material left there. Should be a pretty tight fit, but loose enough so that when released the stem drops from the holder.

If you print the one with sacrificial ends, just snap those off afterwards with a pair or pliers, maybe clean up with a hobby knife.
