Fan switch child cover
thingiverse
Needed a cover for our daughters ( 7yr old) room ceiling fan dimmer/on/off switch. My 2 year old boy kept turning it off/on or dimming/increased light in the room. My daughter has no problem unscrewing the cap and turning the potentiometer. Just used the portion of the screw from the universal spool holder https://www.thingiverse.com/thing:2070272. And made a cap.
