The goal of this puzzle is to assemble the six identical "rib" pieces shown in the first picture into the cage-like structure shown in the others. This is based on the 120-cell, one of the six regular polytopes in four-dimensional space. When assembled the puzzle is a part of the stereographic projection of the radial projection of the 120-cell to the three-sphere.

Each of the ribs is made from five dodecahedral (D) cells in the vertex (v) centered projection of the 120-cell to Euclidean space, and there are 6 ribs each of 5 dodecahedra (6x5=30). giving the puzzle its name.

@gibell Right, this one comes from the vertex centered projection, whereas Quintessence is from the cell centered projection. So they are completely incompatible!

Whew! Finally got my copy together. I didn't realize this puzzle is separate anything in "Quintessence" (unlike the 30-Cell puzzle). The assembled puzzle fits nicely in a golf ball case.

Whoa, six pieces. Somehow, I was expecting five after the 30-cell puzzle!
