Extruder Knob

Here is a simple extruder knob I made to fit stepper motor shafts.
It helps in manual loading and extracting of filament and also shows you when extruder is moving.

I made my own because others crowded the area around the gears making it hard to see if you had filament lined up correctly, with this one you have much more visibility

if you print this please post your photos

print flat side down, no supports.
