A Gear Cube transformed into the shape of Reuleaux tetrahedron.
Traiphum Prungtaengkit has the aim to modify every mass produced puzzle into the shape of a tetrahedron, preferably a pillowed one. In this case he started with a Gear Cube he purchased from Uwe Meffert himself while both were visiting the Rubiks Cube World Championship 2011 in Bangkok.
The modification was made by truncating the puzzle and then filling the holes and gap with black modelling mass.
In 2012 Mefferts started selling a mass produced version of this shape variant.
