A bracket for a filament shelf. It's designed to use two 33.3mm (1 5/16 inch) diameter rods from Home Depot.
I especially like that the bracket doesn't interfere with the filament spools.
The Fusion 360 project is available as well, so that you can customize the size of the rod.
No supports needed. Works well in PLA.
I printed it without top and bottom layers, 9 perimeter walls and 15% honey comb infill to get a nice honey comb pattern.
I used 3 brackets for mounting. The outer brackets were drilled directly into the wooden studs and the inner bracket used drywall anchors.
