I derived this corrugation from Iso-Area Diamond Corrugation by adding some extra space between the diagonal creases. This changes the appearance of the corrugation a lot. It’s a simple change, so I wouldn’t be surprised if others had also folded it at some point.
In nature, there exists a mineral which is a hexagonal diamond allotrope, called lonsdaleite. It’s a rare mineral which occurs in meteorites. However, this corrugation does not represent its crystal lattice exactly since the lattice is three-dimensional and this model is flat, so it is closer to graphite or graphene.
