Patent Puzzle Piece Joints
thingiverse
Amazon (and other companies) gives acrylic puzzle pieces as awards for patents. They can be assembled into flat sheets but that's it. These joints allow you to make 90-degree angles and built more shapes. The two most important joints are FM and FM - Support. You're unlikely to need any of the others. Joints with "support" in the name have additional blocks to hold puzzle pieces in place against gravity (such as for roofs). Coincidentally, they are also the only parts you should need supports when printing. Finally, I am including the base STL of the puzzle piece to help people create new parts. I did *not* create this STL but was given it with a friend along with permission to share it on.
