This file is for a custom potentiometer knob for a guitar. The model is based on the standard Fender Stratocaster knob and follows those rough dimensions, though the knurl is slightly softer. I used Bambu PLA Mulit-Color Silk in Phantom Blue… but if you use a PLA Basic or Matte you won't get any of the layer lines you see on these!

Fit is for the 6mm split-shaft style pot and is push-on. 

These print upside-down, so no supports! Unfortunately there are a LOT of filament changes, so you'll want an AMS and patience. It takes about 1 hr to print 3 of these. There isn't much additional waste in time or filament though for doing more… so make a full batch! The plate is set for 3, but you can always add more.

These fit my 6mm split-shaft knobs with a fairly tight fit…. but for all push-on knobs, the exact fit will depend on your potentiometer and printer calibration. If you find these too tight or too loose, you can easily scale them in Bambu Studio without issue. The default hole on these is 6.1mm ID, so I'd start with +/- 2% scaling if you need. Let me know if you need help and I'm happy to help get these fitting for you.
