The concept of the Penrose cube applied to a pyraminx.
In this case, two edges were rounded, resulting in a puzzle with only two colors. Although it may be possible to make this puzzle by modding an existing pyraminx, the inventor designed this puzzle from scratch using CAD software and then 3D printed it.
Mason designed this puzzle parallely to Antonio Garrido Rubio but presented it earlier. However Antonio's version became the model for the mass produced version (named "Rounded Pyraminx") that is presented in images 8-14.
Size (of package): 85 x 65 x 65 mm
