Replacement knob for 3DConnexion SpaceMouse Compact

This knob comes handy when the soft touch surface of the original knob gets tacky and sticky.

To replace pry away the glossy cap on top of the knob and remove the3 screws. 

I've printed it in PETG but it should also be printable in other materials. Make sure to enable support materials for the screw holes to be supported properly.
