Mounting Bracket

A custom plastic mounting bracket was created that can be printed on a 3D printer. The bracket has two mounting holes which are used to mount the bracket behind a metal plate light switch. The sensors stick through the rectangular hole at the center of the light switch and the board mounts to the bracket using the holes on the sides of the light switch hole.
