Lithograph frames
thingiverse
Two frames for lithographs. 1. "Lithograph Frame 2" and "Lithograph frame backplate" are a little thinner and can be used so the lithograph covers the frame more. Still working on how the back can be removable, but it can also just be left off. 2. "Shadow box" is thicker and has a built in back. 3. "Shadow Box 2" and "Shadow Box backplate can be used with magnets so the back can be removable once the lithograph is attached to the front. Both can also be used just for simple boxes, or use plexiglass for a true shadow box. Printed mine on an Ender 3 Neo, but that isn't an option in the Printer Model yet.
