A 3D-printed square that can be squeezed and bounces back. Four springy links snap together to form a flexible frame: push it into a parallelogram, and it pops right back into a square.
 

How to assemble 🛠️

1. Print the four parts.
2. Clear off any supports.
3. Lay down one link with the spring facing up. Take a second link and press its hole firmly onto the pin. Make sure that the orientation is the same as in the pictures. Don’t be afraid to use some force, that’s what makes the connection strong.
4. Add the other two links at right angles until the loop closes.
5. That’s it, you now have a squishy square.

Coming soon 🚀
I'm currently working on a 3D version that shifts from cube to parallelepiped, stay tuned ;)!
