Even Less Gears is a variation of my Gear Cube and Gear Cube Extreme, both produced by Mefferts.com. Gear Cube is a Rubik's Cube with 12 geared edges. Gear Cube Extreme is a more difficult version with only 8 geared edges. So why not taking this concept one step further and go for just four geared pieces?

You can build your own Even Less Gears by buying a Gear Cube from Mefferts
and add the eight non-geared pieces that you can buy from Shapeways at this page.
