When I first saw photos of this model, I could not believe it was folded from a single sheet, without cuts, folds only:
In case you were wondering, this was WTF (What’s That Fold?) # 8. I was determined to give it a go. Noticing it was made from hundreds of pleats, and given the crease pattern folded down to 64ths in places, I upscaled the suggested paper size (to a 70cm square of 80GSM brown Kraft) to allow for my fat, clumsy fingers to make the creases.
