Tensegrity structures

Tensegrity structures per Buckminster Fuller. Simple 6 strut sphere tensegrity plus 12 strut cuboctohedron. Icosahedron in the works, bug me if interested.

Notes:
- Print the unit pieces in various colors if possible. Print flat side down of course.
- Cuboctohedron has one small angle error that needs to be found and fixed, but it's not too bad.
- You will need some screws to put it together, either metal or plastic, and probably a tap to thread the holes
- Built-in hinge areas require some cleanup with xacto knife for proper operation and a bit tedious so could use some improvement
- Be careful to print the first layer orientation in a direction that doesn't weaken the hinge areas
- Special thanks to author of "Geodesic Math and how to use it" Hugh Kenner for so much fun.
