Mathematical objects not grouped elsewhere, folded as modular origami.

This page lists **models** of a single type. You might be interested in folding instructions instead.

A single-sided surface, the Möbius Band is one of the more interesting mathematical objects that can be reproduced in origami.

A Hamiltonian cycle is a closed path on a polyhedron which visits each vertex exactly once. This model represents such a path for a cube. It can also be used...

This ring can also be worn as a headband. It uses a non-standard way of connecting the modules. Any even number of modules can be connected this way, though ...

This model was quite difficult to design, as the two sides of surfaces made with PHiZZ modules differ a lot (due to the presence of “bumps” where units join)...

This is one of the rather few modular origami designs which require an odd number of modules. Compare also with another similar model.
