This is a set of replacement knobs for my broan range hood. They have the advantage of being larger and easier to grip. For some reason, the old one stripped itself out so I spent some time and made new ones in OpenSCAD.

The source is included, and there is a ifdef statement to switch back and forth between the one for the fan and the light. Also, feel free to remix if needed. To create all the knurling, I used aubenc's Knurled Surface Library v2 (https://www.thingiverse.com/thing:32122). Handy little library to keep in your design arsenal.
