MX Master thumb button refined

Much as stated on the original from Archangel - I've had a couple of MX Master mice and they've all failed this way - the rubber around the the thumb button fails and the switch ends up continuously pressed. This means that the cursor doesn't move/work in any way. I printed Archangel's and liked it - so I sat down and tweaked some of the tolerances - this sits a LOT closer to the edges and conforms a lot closer to the original profile of the mouse. Look at the shot from the heel of the mouse as a comparison./ Shown here printed in PLA Matte black which does the best job of hiding. Build instructions - I followed the instructions on the original - https://makerworld.com/en/models/1011870-mx-master-thumb-button-replacement Solidworks part available as well
