## Sirius ### Interlocking Puzzle by Stewart Coffin (STC #4) Sirius is a pioneering puzzle design by Stewart Coffin, marking the beginning of a series of related puzzles. This innovative puzzle consists of six identical pieces, each with unique color permutations, that assemble into an intricate star-like shape with first stellation of the rhombic dodecahedron geometry. The interlocking mechanism was not invented by Coffin, but he introduced a groundbreaking color scheme that creates striking visual symmetries. Out of multiple assembly options, only two configurations showcase three-fold color symmetry, as seen in the initial photos. ### Printing Instructions Print six copies of `coffin.sirius.stl`, with two pieces each in three distinct colors. Assemble the pieces according to the third image: pair each base color with exactly one tip color, resulting in three sets of identical pairs. This specific assembly is crucial to achieve the intended color configuration. The puzzle pieces are designed for assembly using snap joints; simply attach the male and female connectors without requiring supports. If necessary, reinforce the joints with a few drops of superglue. The models can be printed without supports, making them easier to produce. ### The Printable Puzzle Project The [Printable Puzzle Project](https://www.puzzlehub.org/ppp) aims to provide high-quality open-source puzzle designs for non-commercial use.
