Dr Boo's CR-10 Extruder Dial

thingiverse

I have added 'hand3.stl' which is a loose fitting drop-on dial designed to be placed over a nema-17 shaft. The dial turns with the shaft and indicates direction/rotation, even though it's very loose, allowing for self-seating. This small dial hand snap-fits on top of a 5mm nema-17 extruder shaft. It was specifically created to fit over the CR-10 extruder cover shown in the picture, but can work with any similar shaft. To print this dial, use a slow speed as there's limited surface area gripping the bed.
