My SpaceMouse Pro is only 4 years old but the soft-touch knob became a sticky mess. This is a 2-part replacement.

I designed a replacement in two parts - a hard inner component that screws onto the sensor, and an outer cover that should be printed in TPU so it can stretch over the inside component, and to give you a more comfortable grip than with a hard plastic.
I added more ribs to the outside than the original. But if you want to design your own, grab the STEP file and modify. The beauty is that the inner component with the critical hole placement remains the same.
I used PLA for the inner component but any material will do. Neither component requires supports - just print them upside down (top on the bed) which resulted in a nice surface texture for the outside. For the inner component, I used Orca's "Convert holes to polyholes" which worked but using "Partially bridged" for "Bridge counterbore holes" probably produces a better result. I don't think there's an equivalent in Prusa Slicer.
