His illustration seems to have corners though; that structure looks rollable to me. It seems a bit like the pillow-case problem: how large volume can you get by blowing up a flexible (but non-elastic) square pillow-case? Of course, in this context the important thing is just to make it possible to roll up the casing enough so that you can keep three assemblers and two casings inside an extended casing.
