The unit itself is very simple, and the first thing I made with it was a dodecahedron. But for this exposition I'lljust stick to the above rules.) Or you could make the vertices have degree 4 (I know of two ways youcan do this), and that's interesting too. But the units tend to buckle when forced to do this. has only pentagon and hexagon faces (the faces need not be regular).(Of course, you can break these rules in various ways, say, by makingsquare faces.is cubic - each corner of the polyhedron has three edges meeting it, and.I call it this because you can use it to make any polyhedron that The unit I've been using extensively is what I call the pentagon-hexagon zig-zag unit (or PHiZZ unit). Lots of modular origami unitsexist that fall into this category, units by creators suchas Robert Neale, Lewis Simon, Jeannine Mosely, andJun Maekawa, just to name a few. Of course, other folds in therectangle are needed to make the flaps hook and stay,but that's the basic concept. The short ends of the rectangle become theflaps, and the layers at the sides created by the accordionfolds become the pockets. That is, you accordionpleat a square, typically into 4ths or 3rds, making arectangle. Zig-Zag units aremodular origami folds whose locking mechanismis based on an accordion pleat. Origami Math Pentagon-Hexagon Zig-Zag (PHiZZ) Unit Over the past several years I've been playing with a certain member of the Zig-Zag family ofmodular origami units. ![]()
