This is my design which extends Ilan Garibi’s pineapple tessellation. In this version, the pineapple is larger: the central pleated part is two grid diagonals long instead of one and there are five instead of three radial pleats. Apart from the margins, each molecule is folded from an 11×11 grid, so the whole 4-molecule model with margins uses a 24×24 grid.
Collapsing is a two-stage process like in the original pineapple tessellation. Sheets with larger numbers of molecules will probably be quite challenging to collapse.
