Below, you can find the Crease Pattern (CP) for the unit along with some shaping examples. The CP is very simple, so you should be able to fold it even if you have little experience. The number of notches and the aspect ratio of the strip from which the unit is folded can be freely modified, which allows for a wide variety of shapes, both made from a single unit and from multiple units.
