G500 mouse wheel (beta)

Since the original mouse wheel is quite sloppy when it comes to scolling, I redesigned it with lager bumps on its inner circle to get a more tactile feedback when scrolling.

This version is still beta:
- My friend's printer is unable to print the delicate structures the laser needs to detect the scrolling (the tiny pillars connecting to the inner part).
- I made too few pillars (34 instead of 50).
- This did not work for me, but maybe someone else can get it to work. See my vile prints.
