Extruder knob that can ACTUALLY be tightened - big version
thingiverse
I designed this knob because I couldn't find an extruder knob which could be decently tightened around the stepper motor shaft. Most designs feature a hole in the plastic, which in my experience does not do the job. Therefore this design, featuring a metal nut in the plastic knob. It works. This particular model knob is designed for bowden-drive setups with enough space around the extruder. Requires an M4 nut and screw for tightening.
