Stop your shop light from falling off the ceiling
A simple yet very useful model (to me). I installed these new shop lights in my garage that were wobbling and falling off the ceiling because they're just hanging from two screws. So I made a stopper to keep it on the ceiling and a wedge to keep it from wobbling. Actually, the very first model I ever created.
