impeller rotation indicator

myminifactory

I'm submitting my entry to the Prusa contest, featuring an innovative little impeller that checks whether your filament is fed properly. I've successfully printed one version without support structures, but since I don't own a Prusa printer myself, I created some detailed renders instead. These magnetic attachments fit snugly with 8mm magnets, making it easy to add this feature to any machine. Have fun exploring!
