Tamatebako (origami)

Drawings from a three volume set of wood carvings, Ranma-Zushiki (『欄間図式』, "ranma sketches") published in 1743 by Ōoka Shunboku, featured a colored origami cube.

In 1993, Yasuo Koyanagi identified the cube as the Tamatebako, and the model was published in the book "Koten-ni-miri-origami" by Satoshi Tagaki.

A more elaborate traditional version of the Tamatebako can be made in the form of a cuboctahedron, still using six square pinwheel faces as described above.

Originally, the overlapped triangle was glued together, although it is possible to construct a triangular face hinge that does not require glue.

Like the cube, this form can also be opened from any of the six square faces by unfolding each pinwheel, but will not fall apart if assembled with glue.
