Dimmer Knob

Rotary knob for a light dimmer.

I had to replace the dimmer in my flat. I went to the hardware store, bought one, swapped it over but the old knob didn't work. Went back to the hardware store, bought a new knob, but it didn't quite work. Printed my own. Works fine.

The dimmer I use this with is "LED's light CONTROL Universal Dimmer"

Attached is the Fusion 360 file (so you can adjust dimensions if your dimmer is a bit different) and the 3mf file I used with Prusa Slicer. It was Prusa Slicer that gave the textured outer wall for extra grip. The STL file is just for preview rendering here - I only used 3mf.
