This is a replacement part for the small little slider knobs that break easily on a Hunter Ceiling Fan switch. (Sorry not sure what model it is)

Slice it solid, rotate it to the flat solid surface and print it fairly slow.

I designed this by measuring the original broken part (In the right of the pictures as you can see the slight crack in it) with a caliper and then replicated the part in solidworks.

My design should be stronger since I extended the center support for the length of the part for reinforcement. Enjoy.
