Cst ltrack clickspring

This is an extremely slap-dash approach to getting a clicky scroll wheel for a cst ltrack trackball. The spring might be too tight or too loose in which case I recommend bending it with some heat from a lighter or something.I think I got the right amount of increments with 20 so this should work fine, just hammer some nails in the holes and cut off the heads to mount the scrollbar and stick the spring in the lego cross-hole in the bottom.

Edit: I fucked up counting the increments, turns out it should probably be about 40 because each click generates two scroll events so I'll make a new one with better measurements soon.

Edit2: Some experimentation determined that a better number of scroll events for one full rotation is 48, a new stl is soon to follow.
