American Lobster (Homarus americanus), 2016

This model was in some sense a tribute to John Montroll, who is the first person in origami history to accomplish the same subject from a single uncut square, with the correct number of major appendages, which was published in Animal Origami for the Enthusiast (1985). I try to use the smallest possible grid size to achieve all major features comparable to Montroll's design while making it 3D and optimally efficient. I managed to do all that in a grid size of just 25 (with some half-unit structures). I wouldn't say it's not possible to use an even smaller grid, but very likely the result would be off in proportion.

Anthropods are especially suitable subjects for uniaxial box pleating, hence there's no need to bring ERM into this design. Still, I present the map in the figure above with lakes to show where the body is allocated. One thing about uniaxial box pleating is that in many cases there would be no land at all.

The crease pattern of this design uses a variation of GOPS near the head, which was originally discovered by test folding. The studying of that particular pattern later leads to the discovery of the general transformation rules of GOPS.
