Parametric Stove/Amp Knob

thingiverse

I couldn't find a suitable replacement knob for my camper cooktop. Slicer supports are better than what I got, and they cut off easily with a paring knife. This could work for anything that needs a knob for a flattened or round shaft. With some tinkering in the scad, you can also do a square shaft (decrease the cut to zero and change the $fn for the shaft hole to 4, or replace it with a cube). If I'm having trouble getting the exact shaft diameter and cut right, I can experiment with the shaft_test.scad file and print test fittings to try on my existing shaft: it prints in just a few minutes and uses very little filament. Happy printing...
