This is a little peg which holds on to photographs for display. A wire or string can be ran through the opening to display the pictures--for mine I'm using a led light string. Check out pinterest and etsy for some display ideas. For reference, the peg will grab a piece of normal printer paper that has been folded in half. It securely holds on to the frames of normal Polaroids and Fuji instax pictures. Print with around 50% infill.

These will take a little post processing--the support can be a little tricky to get off.
