This is a bracket/mount for 4-inch recessed lights. We had some left over lights from our home renovation and we wanted to install them in our shop.

The pictures show hole on the side of the bracket which was removed later on to be able to print without supports. Make sure to print in a material that can handle minimal heat. PETG, Nylon or other high heat material would be ideal. I tested PLA and worked ok but the bracket did eventually warped a bit.

Let me know if you need different size.
