I got tired of my 4 year old asking me to turn the bathroom light on for him all the time as it's higher than normal and he cannot reach it.  I quickly designed this to go on a 15mm dowel I had laying around.  This works like a charm and just stays in the bathroom for his use.  Prints super quick on the X1C at just 55 minutes and takes a little screw to secure it in place.  I printed it on the flat side, but you can adjust your print angle as needed.
