A photo holder that fits a photo on a regular photopaper and holds it quite well. It has a little bit of a “break” in the middle, so that the photo is given a bit of a bend - imagine holding a slice of pizza with a bit of a bend near the crust so that it remains almost straight - same principle.

It can be printed on its side without any supports. The model in the photographs was printed with a brim by accident, and that was a bit difficult to detach, and you see its remains on the support. But the bevel is not necessary.
