This is one of three sets of pieces for the Quintessence family of burr puzzles. The other two sets are available here. See the video for more details. The manual lists some of the puzzles that can be built with these sets.
Note that Quintessence is printed at a larger (incompatible!) scale than the original 30-cell puzzle - we had to scale up because of the smaller dodecahedra in the center that are not present in the 30-cell puzzle.
