Here I've made a wall-mountable display shelf for a single Funko Pop! vinyl figure. It is designed to hold a boxed Funko Pop! figure in a 0.5mm protector.

The base is 2mm thick, with a 3mm wall going around to securely hold the box, and a 5cm tall back to allow a couple of decent sized command strips on the reverse.

The back is 5mm thick and feels sturdy, and a 3mm curved brace has been put on the side to add some additional strength.
