12 Piece Arcs and Beams Puzzle

thingiverse

This design is inspired by a wooden model I saw at a friend's house. It's a well-known puzzle that's easy to understand, yet still enjoyable to create and build. To make this puzzle, you'll need six arc pieces and two beams with three slots each, as shown in the filenames. You will also require one additional beam. The total number of pieces needed is twelve: six arcs and six beams.
