I started playing around with the idea of pleats on Rhino. It's important to consider some restrictions of 3D milling. For example, the milling bit has a diameter of 5mm and a height of 3cm, so the gaps between the pleats should be bigger than 5mm and no deeper than 3cm. And it's not possible to mill anything with negative angles since the milling bit only works perpendicularly at this point.
Another thing to consider is that since we are casting bio plastics off of the molds, we are basically working with liquids. So for the bottom mold, I added borders for containing the bio materials better. And the top mold needs to be smaller to fit within the borders.
