I often hang things using tacks, but I grew tired of having to see them or constantly adjust them to make sure they were level. I didn't want to put a ton of holes in the wall either. That's when I came up with the idea of creating a negative volume to use, similar to the screw hole negative volume in PrusaSlicer.
It's a tight fit so you don't need to hold it in there while mounting on the wall. wedge it in the void and hang your object on the wall or wherever you're putting it.
I included the STEP, .Blend .Stl and .f3d Files so you can change it to better suit your needs.
