A skewb in shape of a triakis tetrahedron which is a catalan solid.
For this shape variant of a skewb pieces were designed in CAD, printed on the creators own 3D printer and subsequently duplicated with casting.
The shape is the tetrakis tetrahedron which is a catalan solid and the dual of the truncated tetrahedron. This creation is not the first puzzle in this shape but the first which does not change its shape. To achieve this a mechanisms with the axis system of the corner turning hexahedron (e.g. skewb or Pyraminx) had to be used.
