A 3x3x3 in shape of a hexagonal prism.
This is a cousin of the Hex prism 1. It has the same height but a much small diameter. It can be handmade out of 3x3x3 by truncating six edges like the octagon. These edges make up a continous ring between a pair of opposite corners.
The design for this puzzle was presented in public by Adam Cowan in September 2008. The first sample was presented by Frank Schwartz in December of the same year. The images shown here steem from a sample rebuilt by Eric Johnson presented in 2009.
