These designs are derived from mathematical growth algorithms. I was aiming for mushroom mycelium, but I think they look more like some sort of undersea coral. What do you think?

There are “Small” and “Large” sets: Small: https://than.gs/m/987798 Large: https://than.gs/m/987808

The “Small” download includes six unique models printable within a 100x100mm build volume.

The “Large” download includes three unique models printable within a 250x250mm build volume. These large models have more asymmetry around the outer edge.

All models are thicker in the center so that printing with transition filament will give you some interesting radial color gradients.
