Hanger rod holder bracket

prusaprinters

I needed to mount a rod as a hanger for clamps on the front face of a shelf. So I designed one. The one shared here is the 3rd iteration. The first two did not make it into a printed object. This one works, but can be definitely improved. Print instructionsI used Philament PLA in White. 15% infill, 4 tops, 4 bottoms, 4 walls. I am sure you could get away with less infill. Supports were used only in the overhangs on the shelf side, not for the holes. It is designed for a 18mm thick shelf. Mount holes are designed for a size 4 wood screw and the rod hole is for a 8mm aluminum rod. I used a 8mm by 1m hollow aluminum rod. There was enough sagging in the rod when loaded that I printed a 3rd bracket and mounted it close to the middle (had a specific location), now it holds well enough.
