Hi Shapeways fans, Star Beams is a put-together interlocking puzzle. The puzzle has six pentagram-shaped beams that are woven through each other. It was in 1989 that I discovered this geometry. It is based the geometry of a regular dodecahedron (with twelve pentagonal faces). When each of the six axes is offset a bit, this nice tetrahedral geometry results. In 1989, I made a cardboard prototype with pentagonal beams. In 2004, George Miller 3D-printed Star Beams on his 3D printer. Now, it is available as 3D-print from Shapeways and sold by PuzzleMaster.
