Rubiks Snake

I had originally planned on doing a rubiks cube but its been done already so I thought I'd try rubiks snake puzzle.

The 45 degree overhang makes it difficult to model in few parts so it's actually quite a lot of bit to assemble (on average 4 parts per link)

I don't know how well it will print or assemble, when I get my bot I intend to run a test (one of the many) and try some different sizes.

I've included an SKP file with the 4 basic parts in case anyone wants to suggest a better way of joining the prisms.
