This is a frame for photos or art. The pieces lock together using tabs. All the pieces print with no overhang issues.
Print two long pieces, two shor...t pieces, four corner pieces, and four lock pieces.
The four lock pieces are inserted in the sockets in the four corner pieces.
All the pieces should fit together firmly but, a bit of glue will be
required to keep them together. Note: The inside corner of the corner
piece has a thin piece of breakaway support that has to be removed.
