Designed to fit over standard Toggle Wall Switch. One bathroom in our house is Rubber Duck themed. Still have to paint it.
Any Billy Madison fans can print in Blue, I had black already in the printer and planned on painting it regardless.
Can be mirrored to face the opposite direction.
I printed at 0.2mm layer height, 20% infill. I designed the brim into the model because the default brim goes in weird places, so just have to trim off once done.
