Hanging Wall Modular Photo Frame

This is a 10mm x 15mm photo frame that you hang on the wall with a nail, It comes with a back plate and a hook to hook in the bottom to add another frame. There are vertical and horizontal frames and you can mix them up. The back plate is compatible with both frames. On a small plate like mine (220 x 220), I could print the back and vertical plates together but not the horizontal and back plates.

The back plate is printed with the hook but you can remove it or add more hooks and print them in different colors. I printed it on an Ender 3 V3 KE.

Please post makes.
