A 3x3x3 that allows swapping of centers with edges.
This puzzle was invented and patented in 1985 by Sergey Makarov. It was made as one-of-a-kind and never made it into massproduction. Back then it was named "Makarov's cube". In 2009 a new version shown here was designed by Oskar van Deventer without knowing the 1985-version. For more information see the "Hedgehog Cube".
It looks like a Rubik's Cube, but it has an unexpected twist. When a mid plane is turned by 45 degrees, other turns are possible. This way of turning mixes up the center and edge pieces.
In 2013 Witeden presented (in collaboration with Oskar) a mass produced version of this puzzle. Before there was only the version from shapeways.
This new version has an edge length of 65 mm.
If you're looking to buy, eBay is the one place you can find almost anything... if you're willing to wait for it, then pay the price!
