Here is a small shelf for displaying collectibles on a wall that I created. It may require some light weight wall anchors just to make sure it doesn't pull out of the sheetrock. The main shelf is designed to be printed without supports, but the bracket will need some support for the recessed mounting holes. From my slicer, I added a small 9mm x 9mm custom area around the mounting holes on the bracket to make them 100% infill for a little more strength.
