Stormtrooper Ender 3 Control Knob
thingiverse
Remixed from - ProCoPrint3D's Stormtrooper Helm I recommend rotating it upside down for easier support removal later. I personally have not tested this file so print at your own risk. The updated file has a tighter potentiometer fitting so that the rotating of the knob feels smoother. Also updated with stronger fitting so that they are not as fragile.
