Here's some vinyl wall mounts I whipped up after not finding any that I wanted. Super easy print with a little support on the sloped bit. There's a nail hole at the top that is countersunk and fits those small picture frame nail heads but I'm sure some tape or something on the back would work also, though I haven't tried that so do it at your own risk I guess. I hung them with about 2in on each side of the vinyl and it seems to work out good. I wouldn't go too much further inward however.
The author marked this model as their own original creation.
