My 2-year-old loved to climb up on the arm of the couch and play with the overhead lights and fans. Hopefully this deters her!
Printed in BamTack! White PLA, which matches my white switchplates almost perfectly.
See my remix, http://www.thingiverse.com/thing:2010893, for the version pictured. It enlarges the holes and adds countersinks, plus rounds the ends for a cleaner appearance.
Note that I printed without supports, which caused the bottom side of the rounded end to get a little messy. Print with supports to help prevent this if you care (it's only a minor blemish as you can see from the photos).
