I made this so that I can give this as a present to nieces and nephews. The other light switch plates take a long time to print out >14 hours. This light switch plate takes about 4.5 hours with a 0.2mm layer and 55% fill density.
Three of these should fit side to side on a 3 light switch plate. (Comment if you try it out please!)
2 should fit side to side on a two light switch plate.
I printed it out using Brim and supports touching the build plates. It doesn't need support everywhere to print out correclty.
You might need to clean up the snap fit with an exacto knife.
Slide it on
Cut off the Brim. Note* the back snap support is the same thickness as the brim so be careful when removing it. I cut the brim off with a scissor.
Remove the supports
Snap gear into place and slide the pinion into place.
TURN OFF THE POWER TO THE LIGHT SWITCH.
Remove the current light switch plate
Slide the fixture onto the existing light switch plate.
Put the plate back on the wall.
Turn the power back on.
