I designed this knob as a replacement for the original one I broke as you can see on the last 2 pictures.
If you fancy modifying the model I've included the STEP file, feel free to share and remix but do not sell please.
Printed at 0.15mm layer height but resolution is really entirely up to you, even though it was designed with 0.2mm layers in mind.
Filaments used are Prusament galaxy grey and galaxy black.
The included GCODE has a color change at layer 6 or so in order to have a different color for the arrow pointing at the power level on the fan dial.
The author hasn't provided the model origin yet.
