This is a four sided picture holder I made for a school event. It was used as a centerpiece, with pictures on all 4 sides, the table number on the clip on top and balloons tied to the clip.
The slots for pictures are 5.5 cm square, the viewing space for pictures is 5 cm square.
It prints in three pieces so no need for supports, I printed to clip with 100% fill to make it sturdier.
The clip fits snugly onto the top so you don't need to glue it, this allows you to take it out and store flat to reduce chances of breakage.
