Our friend Paul Kinsky uploaded his algorithm that generates sheets of polygons and connectors that can be laser-cut and connected with cotter pins to form arbitrary 3d surfaces. It takes .OBJ files as input and outputs DXF files.
He emailed me this amazing work and said, "I made an algorithm that takes as input a 3d model and outputs pieces that can be pieced together to make a real life version of that 3d model."
