Windmill Extruder Knob
thingiverse
After updating my E3 to a Hydra Direct Drive, I felt like a nice knob was missing for my All-Metal extruder axis. I couldn't find any proper Windmill, so I remixed Petclaud's (= Still haven't printed those, but they'll be showing on the printbed soon enough! I'll update here with pics later =)
