Auto shutoff switch knob
cults3d
This knob fits on a timer switch like the ones you find at most hotels (they control the heat lamp in the bathroom) I work at a hotel and the maintenance guy couldn't find replacement knobs, the originals apparently break easily. I've printed with various types of PLA with no issues, no support required twenty percent infill works well for me.
