Prusa MMU2 Pulley Stepper Motor Knob
Description
I designed this two piece knob / thumb wheel to help me rotate the pulley stepper motor with my fingers as I clean the hobbed filament pulleys / drive gears from shredded filament bits with a needle or toothbrush. Works great. You will need (2) 3mm x 10 screws and (2) 3mm sq nuts which should be in your Prusa spares bag. prints with no raft or supports. PS - I've been told this will not work with the MMU1 to MMU2 upgrade as there is a metal coupling in this area. Fusion360 model included.
