Another strange shape for the 3x3x3 which does not bear a proper name but only an index. This shape is special because it is self-dual.

This is a shape variant of the 3x3x3 which was completely 3D-printed on the inventors own printer.
This shape is one of the few known shapes which are self-dual which was the reaon for the inventor to implement it.
The shape has 24 faces which are identical 6/2-gons.
The shape has hexahedral symmetry and therefore the puzzle does not change its shape.
Edge length: 65 mm / 115 mm
