More flexing cubes

The Yoshimoto Cube is a marvellous folding and flexing toy originally conceived by Noaki Yoshimoto in 1971: here’s a video of the whole set of 3 interconnecting cubes.

The set can be obtained here: worth investing in if you’re a Yoshimoto fan like me!

You may be familiar with my origami version of Yoshimoto Cube 1, which I wrongly titled Double Star Flexicube in Brilliant Origami: this was before I knew the correct name for it.

Two ingenious new approaches to the challenge of an origami Yoshimoto Cube recently caught my eye. The first is by Olga Amimono:

Olga says:

My method is almost modular origami – it is necessary to make 12 identical modules and connect them inserting one into another (but 4 modules are to be cut in half before assembling). To avoid cutting (because generally cutting is prohibited in origami) alternatively it is possible to fold 4 “left” and 4 “right” modules using half-sized paper. But making 12 identical modules seems more beautiful for me. 
In comparison with your method, this new method has several pluses: use only one paper size, only 12 parts, and what I like most – it is strong, none of its parts fall apart if you play with it. There is strong connection in the place where 6 small triangles touch each other, and strong connection between all 8 parts.
About me – my name is Olga, I am Russian living in Japan, Chiba prefecture. I am interested in mathematics, I like different polyhedra and geometric patterns. I was not related to origami before, except for “Japanese cranes” and “little boats”. My first origami model was “Origami cube that can move, how to make without adhesive”   It is the model that uses Sonobe units and extended unit that is used for strong parts connection.
Olga’s you tube channel is worth exploring:


Another great origami Yoshimoto Cube version is by Yuki Honma.

Yuki writes:

I am the owner of a wrapping paper online shop in Japan.

I am making videos how to make pretty and useful boxes, bags and etc. out of wrapping paper. I am very excited about folding Yoshimoto cubes recently. When I was a kid, I had toys something like that, but I got bored soon. But now although I am almost 40, I can play with them forever. One reason might because they were made by myself. I want other people to experience the feeling, too. And also, I want to design a new 3D puzzle model by myself.

Have a look at Yuki’s youtube channel which also has many interesting ideas to try.

Finally I was intrigued by a rather similar flexing cube toy called the DynaCube.

After some fruitless expriments I have acheived an origami version using Brillik Cube units: see if you can work out how I did it.


Great fun to be had by all with flexing cube toys!
