Nine Nonagons: Grid
When designing the grid, I realized that the best lines for efficiently locating every necessary intersection of the crease pattern were all going in three directions (like a regular triangle grid). So I decided I would aim for using such a grid for simplicity sake.
However, in order to obtain the correct grid creases at seemingly random intervals from each other, it was first necessary to create reference points for generating the grid itself.
Thus, I created a pre-grid that must be folded in order to fold the actual grid, whose lines are all going at multiples of 20 degrees except for the lines parallel to the long diagonal which are at 30 degrees (the 20 degree creases require angle trisection of the 60 degree angles).
