MX Master thumb button replacement
thingiverse
My trusty Logitech MX Master thumb button started not working as it used to so the very first time I disassembled I was following a youtube video where the guy slightly unscrewed the mini PCB where the temporary switch is located. For several days it worked but suddenly I noticed that the mouse pointer was not working but instead all the macro gestures were activated so I knew that again was that thumb button that was stuck. Meanwhile the rubber started cracking due to the continuous activation of the button... I really didn't want to dismiss the mouse so I decided to design a replacement by myself.
