Seamless Cube

In "literature" several models of a seamless cube are known ( Kasahara and Takahama, Haga, Montroll, Ewing, Shafer);

they are very similar, with slight variations.

All these models starts from a 4 x 4 square grid, and use the same locking mechanism (a 3-flaps close system).

Personally I don't like this 3-way locking system, it looks to me a little bit weak, and edges tends to relax.

So I've designed this model, that starts from a 4.5 x 3.5 rectangular grid, and use only one closing point, with a rectangular flap.

I guess to diagram it in the next weeks.
