Another variant of the Rainbow Cube, this time in the shape of a tetrahedron.
This is actually the fourth Rainbow Cube in shape of a tetrahedron. Unlike the predecessors all eight corner pieces are visible and four of them have a visible orientation. The edge pieces of the Rainbow Cube come in shape of segments and in sets of three segments with the same colours. Not that it matters in such an easy puzzle.
In 2019 Kevin Uhrik designed his own version "Coin Tetrahedron" shown in images 6-8.
That version went into mass production in 2020. See images 9-11.
Edge Length: 96 mm
Weight: 114 grams
