Since I don't have access to Command Strips I decided to remix HighFiveGhost's wall mount to be able to fit thumbtacks through to mount it.
I don't really have any idea how much weight they can hold. I've had mine up for more than 4 months holding either double LPs, they don't seem to have budged.
The printed examples in the pictures have been done using AmazonBasics PLA Blue (for, well, the blue ones) and Polymaker PolyTerra Charcoal Black.
