Is it possible to build 3D toys connecting several LEGO Bricks sticks/rods to make polyhedrons? Lengths and angles between sticks should be variable.

1 Answer 1


You mean like these lovely polyhedrons?

  • Yes, they look great! Can they be made to get fixed in any set position? Is it possible to make a user defined rigid net of convex hull like Fuller domes?

  • There are several style of hinges available. The first 5 listed on that link are nice, and adding Hinge Plate 1 x 4 to the mix might give you everything you need. Anyway, tons of hinges to explore...
