Modular Balls and Polyhedra
Balls and polyhedra are among the most common forms modular origami models take.
This page lists models of a single type. You might be interested in folding instructions instead.

Rhombicuboctahedron with Triangular Faces Left Out (BBU D4)

Expanded Hexagonal Prism
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...

Truncated Cuboctahedron with Inverted Spikes on Octagonal Faces
This is a physically large model which demonstrates how StEM units made from sheets of different proportions can be combined (obviously, all rectangles’ shor...
Toshie’s Jewel (StEM)
Normally, Toshie’s jewel is made from Sonobe units, but this one is made from StEM units instead.
Octahedron with Inverted Spikes on all Faces
This model’s structure is an octahedron whose each face was replaced with a pyramid of three equilateral right triangles, pointing inwards. Units are located...
Icosahedron with Inverted Spikes on all Faces
This model shows how StEM units can be modified so that their short rather than their long axis is aligned along the model’s edge.
Tetrahedron (StEM)
This model (first from the left) is compared here with some other simple polyhedra folded from the same kind of module. Note how the tetrahedron looks almost...

Truncated Octahedron (Open Frame Unit)
Made from Tomoko Fuse’s Open Frame I (bow-tie motif) unit, polyhedron design by me.
