Six Piece Octahedron Puzzle

This is a dissection of an octahedron into six identical pieces.  Assembly is surprisingly easy, given that it is coordinate motion.  The puzzle does not interlock very well, which helps.

The octahedron has an edge length of 6 cm. If you print two pieces of each color it can be assembled so that every face has all three colors. The piece is Piece 6 of Octahedrik.

The piece has an edge against the build plate, so supports are required. The supports in the 3mf file work well.
