Fan Knob

thingiverse

It is hot these days in Europe. We found this old Chinese fan, that brings us some moving air now. Unfortunately the knob for turning on the fan and adjusting the speed of it was missing. No problem with a 3D-printer. I made a quick and dirty design in OpenSCAD and the first print works like desired. I assume the exact knob is not compatible with other fans. The dimensions of the shaft are depicted in the schematic picture. However, I share it here with the source code, so it is easy modifiable. It is not prepared for the Customizer, but it should be easy to modify it directly within OpenSCAD.
