Extruder knob that can ACTUALLY be tightened - small version by Creappie

Last crawled date: 4 years, 6 months ago

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 direct-drive setups with very little space around the extruder. I will post other, bigger, knobs later.
Requires an M4 nut and (short) M4 screw for tightening.
