Knurled Knob for KY-040 Rotary Encoder

Print twice off here. One is huge and loose, the other is works okay but a tad too deep for the switch to trigger correctly.

So took the chance to design my own while learning how to knurl with Fusion360.

I hollowed out the center a bit to save filament.

• diameter: 28mm
• height: 20mm

Update:

• v3: thinner side, thicker bottom
