Angled design holds heavy loads without the need for a huge hole in the wall. Just Insert a thin long brad, or piece of piano wire, and hammer into your drywall. Prints flat also. After removal hole is easily repairable (toothpaste not included), I have included two extra preliminary designs with/and without a stabilizing flange. Lastly, you might want to scale it up about 25% if you have large hangings.
