About this model

This is a spin (pun slightly intended) on George Hart's cube puzzle. In his puzzle, he dissected a cube into two pieces with a spiral-like surface called a helicoid. The resulting two pieces are identical, and are themselves 2-fold symmetric. I played with this idea on some of the other platonic solids. I cut an icosahedron into two equal and symmetric pieces with a helicoid. Going further, if you have a solid with a 3-fold axis of symmetry, you can cut it into 3 equal pieces with 3 helicoid surfaces. I did this with a dodecahedron and an octahedron. Note that these polyhedra also possess 2-fold symmetry axes, and so can be cut into 2 pieces as well. I included the Python Jupyter notebook I used to create them. I was using SolidPython, which is essentially a Python wrapper around OpenSCAD.…
