Origami Duck

A harder model than the Origami Ship http://www.thingiverse.com/thing:753562. The customiser allows some angles and the 'paper' thickness to be changed. The code needs to be edited to change the vertices which are taken from an actual fold. I had to figure out how to fold along arbitrary lines so the model remains connected when angles are changed.

The origami model is by Robert Lang - see my blog http://kitwallace.tumblr.com/post/65603134110/day-3-origami

As I attempted to fold the faces, I was surprised to discover that some faces of the origami model are not actually planar. So there is an extra fold in the neck to accommodate one such.
