About this 3D model

I lost one of my Campingaz Basecamp gas regulation knobs, so I made this one. The trigonometry in the SCAD file is somewhat buggy, but it should be a starting point for what I think is an unpretentious but beautiful, average, no-fancies knob of any size. The printed stl feels rather sturdy and it sticks quite tightly to my burners axis (without glue).
