This is a rotatable 5”x7” picture holder. It can be glued together, but this one is held together with only a bolt, washers, spring washer, and locking nut in the center. The individual frame holders are held on with small screws, washers and nuts. When done the pictures can be rotated around the hub, and at the arm ends. The grey parts in this model are PLA and the one red arm is PETG. The frame holders are a remix of Tosh’s “Floating photo frame” printed at 90% scale.
