Westinghouse Space Heater power knob

thingiverse

Our $15 space heater had seen better days. It had been kicked over so many times, the poor thing had developed permanent internal injuries. One was a cracked knob that made it impossible to turn it on and off. I measured the spindle and recess compartment, then printed a succession of knobs until I had one that fit tightly and worked satisfyingly. It only has two markings - you are welcome to add more if you like, but for me it's good enough to mark "Off" and "High". The in-between settings are easy enough to remember.
