Wanted to add a more personal touch to my printer so I made a simple knob to replace the original.

The knob has gnurling around the outside to improve the grip. The overall size of does not interfere with the back button beneath it.

I've uploaded both the blank version and the version with my gear emblem. The color change was done manually at the start of the detail layer.

If you're looking to make your own custom design I'd recommend keeping it relatively simple as the small size of the knob will limit how much detail you can get.
