On Tony Fisher's version, though, there was a problem when after 30° turn is done, babyface pieces can fall off during incomplete moves.
In 2011 Tom van der Zanden presented a completely new design which can be purchased through a 3D printing service. Beginning in 2012 mass production of Tom's version started.
This version comes with six differently coloured bodies:
black, white, blue, checker I (blue & white), checker II (black & white), transparent with 12 colours (see image 6).
