This is a simple, customizable, wallmounted fotoframe.
@Pixelrichie made a simple but nice photoframe that didn't fit my photosizes. I redesigned it with variable width and height. The thing found here is for 13x18 cm pictures. Copy my onshape model here enter your width and your heigt (variables at the top) and export as STL.
it might print better with PLA as the overhangs work better.
