But at http://www.shapeways.com/model/170988... Copyright (c) 2010, M. Oskar van Deventer. Gear Skewb is based on the well-known tetrahedral/octahedral Skewb geometry. Twenty-four gears guide the rotation of this puzzle.
This puzzle was 3D-printed using nylon-powder SLS technology, which explains its price. It is the very first prototype, costing its designer and maker a lot of money to create. Please do not confuse it for a cheap mass-produced puzzle.
