Yoshimoto Cube

The Yoshimoto Cube is a mechanical puzzle toy that was invented in 1971 by Japanese inventor Naoki Yoshimoto. This polyhedral puzzle consists of eight interconnected cubes that can be folded and unfolded in a cyclic fashion indefinitely. Once folded, the cube can be transformed into two rhombic stellated dodecahedrons, which can then be combined to form a square. Yoshimoto discovered this property by experimenting with different ways to split a cube equally in half. The cube's unique design allows it to be reconfigured and rearranged, making it an intriguing puzzle for enthusiasts. Recently, the Yoshimoto Cube has gained attention from makers and DIY enthusiasts who are interested in 3D printing and creating complex mechanical designs. As suggested by Michael Ragan, one possible next step is to design a printable mold that can be used to create multiple units of the cube's components, which would make it easier to assemble. To create a Yoshimoto Cube, you will need to print out 16 parts using a 3D printer. You can then assemble these parts by following the instructions provided on Instructables. The assembly process involves printing and sanding down the parts, applying a releasing agent, and taping them together before pouring in resin. Alternatively, you can use a hot glue gun as a filler material to create the cube's components. This method is faster and cheaper than using expensive resins, making it an attractive option for makers on a budget.
