Whirlwind Tessellation

Whirlwind Tessellation

A box decorated with a molecule of Whirlwind Tessellation

Precreased sheet for the box — the central 8×8 square is the precrease for the molecule itself (see also text for details)

You can figure out how to fold a molecule of this tessellation based on instructions for the Stacked Whirlwind Molecule.

For a clean fold, you can use the precrease pattern shown here. The whole sheet is the precrease pattern for the box, based on a 16×16 grid. The central 8×8 part is the precrease just for the tessellation molecule. Disregard the error I made while precreasing, two unnecessary creases which break the symmetry and only appear in the lower part of the pattern. The pre-creased lines which abruptly end without meeting any other creases are the result of this model using curved folds, which are not precreased, and the model being 3D. Obviously, in a complete PreCP of a flat-foldable model, such creases could never appear.
