MX Master thumb button replacement

SummaryMy 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. DISCLOSURE!!!1 - This is not intended to be the final work as it can still be improved!2 - If your button is still intact, PLEASE DO NOT PROCEED as it will require to completely cut the rubber that stays on top of the mini pcb...ONCE YOU CUT THE RUBBER, YOU ARE DONE...OBVIOUSLY.3 - THIS PRINT NEED A WELL TUNED PRINTER WITH SPOT ON DIMENSION - DO NOT PROCEED IF IT'S NOT AS IT WI
