Description

One of Stewart Coffin's most well-known design.  Surprisingly tricky considering there are only 3 pieces.  The target shape is a tetrahedron made from cubes, definitely a difficult shape to visualize.

This copy was 3D printed by Shapeways, it is "pocket sized" and made from ten 13mm cubes.  Each piece is dyed a different color, which makes disassembly easy, but reassembly is not any easier.

I have several wood copies of this puzzle, and while they are very nice, none of them fit as well as this puzzle.  The fit should also not change with humidity or time, and the joints should never break.  This is a good puzzle to show others because you don't have to worry about it getting broken.
