Josef Prusa Stepper Motion Indicator

I couldn't sleep and I thought this was funny. I used a 3mm magnet and a smaller one (IDK what size) under it to make it spin best. The filament string is just that: some 1.75mm filament. I attached it via some 3M VHB tape. Perform a color change so Jo shows up. The small bit holds the filament in place and I printed it in black, but should probably just match whatever color you make Jo.

Have fun!
