Cherry MX SwitchPlunger & Spacer for Seimitsu 30mm PS-14-KN Button

Edit 3/26/2021

Added a v2 plunger. Made it a little bit taller to it doesn't rattle as much and modified the geometry of the stem. Left both versions so you can print out both and decide for yourself which one fits your needs. 

If printing with PrusaSlicer use variable layer height and print the last part of the stem with the smallest layer height possible. This will make it fit to the micro switch a lot better.
