Tetrapod Puzzle 1

thingiverse

Form a wave-breaking tetrapod block out of four pieces. The pieces are identical but two of them are mirrored. Print two pieces, A and two pieces B. This puzzle is not very difficult, but if you give it to someone who doesn't know what it will make, they might have some trouble figuring it out, and be surprised by the final shape too. Print with concrete filament at 100X scale, and place along the coastline to protect from tsunamis.
