Small simple photo frames

Wanted to make some art pieces to hang above my cats' feeder so designed these small frames quickly. The little holes/nubs are only to properly align the two pieces; I used contact glue to secure them together. They then accommodate half of a 4 x 6 acrylic piece so two frames can be fame out of a single standard piece. Printed at 0.15 mm with no supports; just orient the pieces properly.
