This file is for a custom potentiometer knob for a guitar. This knob is single-color and has a large knurling pattern on the underside for grip.

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

These print upside-down, so no supports! This helps give an excellent surface finish on the top, which I think looks particularly nice on this style with the concentric surface pattern. Would also look cool to use with one of the fancy build-plate textures!

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.
