Octahedron Beam

http://www.3ders.org/articles/20121201-ultralight-3d-printed-beams-could-bear-heavy-loads.html Modeled after the article. Done with blender using the skinmodifier. I hope I will be able to use it on all skales instead of normal rectangular beam. Next: I will try to add a version which is repeatable with connectors on the ends.
