Nema 17 Knob
thingiverse
The knob is used on the filament drive system at the end of the nema 17 stepper motor to help feed the filament through to the extruder. The knob is locked onto the stepper shaft using a 3mm nut and cap screw , remember not too tight or it will break! The finished knob looks not to bad and YMMV!
