The original knob for this oven wouldn't stay on, and eventuall got melted when it was left on the stovetop. So I designed this replacement in OpenSCAD. This is the first version that I've printed, and it could use some modifications if I print another. It doesn't push on quite as far as the original, and the dimensions are a little different, but it works pretty well. The metal ring with the settings printed on it will fit on this as well. The original had little tabs to keep it aligned, but I decided to leave them off.
