The key here is scale. What works in inches often falls apart at feet. The structure is holding about 33 psi over the area (which is rigidly supported from below), much more along the contact edges. By comparison balsa wood can support significantly more pressure (varies, but well over 100psi) but doesn’t concentrate pressure on edges.
Is there anything useful about this? Maybe as an inexpensive(?) core for high strength skins?

Does that mean we could increase the orders of magnitude if we made it smaller? Lots of tiny stuff needs mechanical support. And lots of folded small things agglomerated is another way to say biology.
