I like to keep my keys near my light switch so I have a convenient place to place when I come home. I lose my keys if I don't have a good place to keep them.
The hinge can be printed in place and the model doesn't need any supports. The screw hole allows for easy install with the same screw used to mount the place on the light switch. STL file has model already positioned for easy printing.
The author marked this model as their own original creation.
