This is a light switch frame for a children's room. I have attached the DWG file so that you can customize it to fit your own light switch.

This is for a 75mm x 126.5mm light switch frame. It has been made it slightly larger to account for the printer inaccuracy and currently snaps on perfectly around my existing switch.

You could possibly use putty or a hot glue gun to attach the frame to the switch and wall.
