Create your own photocollection, using standard passport photos (45 millimetres high x 35 millimetres wide) and slide them on either side of the 3D printed photoholder. You can also slide on either side a piece of standard size paper, used in e.g. Atlanta maps (see photo 7), containing the name of the person on the passport photo.
Just use your imagination to build for example a wall of photos, a tree for your pedigree photos or just a single photo-frame!
