Took the excellent wall hook created by Finch, and added the option to use peg-board L-hooks. These are fairly snug, and once they're pressed into place, they hold the whole device pretty tightly against the peg-board. I diddled the slots on tinkercad so I only have the .stl file available. Bless tinkercad for providing a tool that we rank amateurs can take advantage of to modify the work of you more creative types.
