Two years ago Mark and Karl-Heinz designed this one
http://twistypuzzles.com/forum/viewtopic.php?f=15&t=17995&start=0&hilit=3x4x6.

Greg said some weeks ago, that it is possible to make it proportional.

Today I can show the result:

Greg's FF 3x4x6 cuboid

See the video - no more words: http://www.youtube.com/watch?v=wX5FGz84pQQ

Nice work. It's a beautiful puzzle. The only thing that put me off making it was that it had already been made before. Great stuff guys! :D

The core is a 5*5*15 ! You can't make a proportionnal 5x5x15 unless shapeways wall thickness is brought down to 0.1mm or less ! :P

EDIT: Claus, the reason this can be proportionnal is because it is a cross 3x4x4, and two factors allow proportionnality:
1) the 3x4x4's proportionnal
2) 3x4 faces are circleable.
