Grip-Style Thumb Button for Kensington Expert Mouse

thingiverse

This is a simple mod for a grip-style thumb button for the Kensington Expert Mouse, similar to an Elecom trackball or Logitech Trackman Marble. The file contains 4 thumb pieces of varying sizes. The one I found best was the smallest one, shown in the pictures. I used mounting putty to stick it on and test it out for a temporary to semi-permanent solution. For a more permanent solution, use thermoplastic instead.
