## Dodecahedron (Penultimate Unit)

A regular dodecahedron made from Penultimate Unit, designed by Robert Neale. These units are very simple to fold and very versatile.

Models representing all sorts of polyhedra, including roundish ones (spheres and other smooth shapes can mostly only be approximated in origami).

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

In this assembly method, units forming each face of the cube are woven, forming a hole in the middle. This increases the number of units needed for a cube to...

This model demonstrates how Building Block Units can be modified to form rectangular rather than square faces. Just like the cube, this model uses 12 modules...

This is a shape created by placing cubes on the outer square walls of a hexagonal prism. This way, the outer outline becomes a dodecagonal prism. Seen from t...

Due to the E10 tile’s small flaps, it can’t be directly attached to the flaps of inner A1 tiles. An additional “sizing” layer of A2 tiles is needed for prope...
