Gear Shift is the creation of Bram Cohen & Oskar van Deventer. The official description: Gear Shift is based on an idea by Bram Cohen. This puzzle has eight gears around a cube. All gears can turn together. But it is also possible to pull the gears apart in two sets of four. Each set of four can be turned individually. And there are three ways to split the gears. The object of this puzzle is similar to Rubik's Cube: scramble it and then try to solve it.
Yesterday, I toyed with Gear Shift for about 45 minutes. Came up with an idea, implemented it & solved the puzzle. I do not fully understand this puzzle's mechanism.
As custom 3D printed puzzles go, this one is priced well: $133.40 Order yours at Shapeways
