Below are the instructions to make your own modular origami octahedron. In my opinion the simplest modular origami polyhedron.

These modules require very little folding. Unlike, say, the Sonobe Unit.

I make octahedra regularly. It is the easiest modular origami polyhedron to make. But this one at ~22nm is a lot smaller than I've ever made!
