In my closet, I have a few of these brackets from Home Depot for holding a shelf and closet rod. Over the years, a few times, the original nylon rod mount has bent and caused the rod to fall to the ground. I designed this piece to replace the mount, with a deeper socket and thicker walls.
I printed these in PLA+ with 6 perimeters and 99% infill, then annealed them at 90C for 2 hours. I've had them mounted for a few months now with no deformation.
