Yoshimoto Cube developments
The wonderful Yoshimoto Cube has fascinated me for many years – ever since Paul Jackson showed me a papercraft version ages ago. I recall that Thoki Yenn had a try at an origami version, as did Kuni Kasahara.
It was Dave Mitchell’s Stellated Rhombic Dodecahedron, based on the classic wood block version (fig 88) that gave me the clue to resolving the origami design which I called the Double Star Flexicube. The title was given before I was aware that the originator was Naoki Yoshimoto.
In fact, Naoki Yoshimoto designed three related and interconnecting cubes which are shown on this video. You can buy the whole set from here.
Recently I revised the units so they can be folded from squares, to provide an extra lock, and I made the replica of YC1 seen at the top of this page.
The next development was to build the half cube sections from single sheets, which means that is the construction is stronger, but much more difficult to build.
I’ve managed an origami version of YC2 also. Not too difficult to fold, but not so spectacular as YC1.
I’ve yet to try YC3…
