Matthew Bahner is a geometrical puzzle enthusiast who enjoys bringing his designs to fruition with 3D printing. His latest design is an evolution of the Rubik’s cube, with his variation being on that of the V Cube. Bahner’s complex puzzle cube has set the record as the world’s smallest 7x7x7 puzzle cube with a width of 3.4 centimeters. Bahner designed it with CAD software and after two designs and some refinement, sent it to Shapeways for 3D printing.
