I am ordering test prints today (in a bunch of different materials) of my series of coral-inspired models. They are basically all the same model, but are sized to to have similar price structures. Additionally, the WSF model has been hollowed in order to make it larger. And both the WSF and Ceramic models have the three base nodules cropped.
The model was generated with a single mathematical expression using the implicit surfaces filter in MeshLab, and has 3-fold rotational (trilateral) symmetry.
