Infinity Cube, Magic Cube, Flexible Cube, Folding Cube for Flexible TPU filament

3D model description

Infinity Cube, Magic Cube, Flexible Cube, Folding Cube

Yet another experiment using TPU—the magic/flexible/folding/infinity cube or whatever fancy name you could think of. In this 3D design project, I took account of the tolerance between the little cubes and the bending connectors among them using chamfer and grooves. It can be printed in one piece. The result goes beyond my expectations. It comes in three sizes: 20mm^3, 25mm^3, and 30mm^3.

In light of the complex navigations and physical constraints, this should make an interesting intermediate design project for students. In my case, I first made a huge model using 48 polydron squares and adhesive tape before sketching them in Fusion 360. With parametric design, you could easily change its dimensions. Have fun!
