thingiverse
Two knobs, a round one, and a selector for small switches, similar to what you'd find on a guitar.
The switch is designed to press-fit onto a switch that is 3.91mm long, and 2.6mm long.
Instructions
You can edit the "fudge" variable in the OpenSCAD file to accommodate your printer.
I have a .4mm nozzle, and my "fudge" variable was perfect at .2, or half of the nozzle size.
