Press into damp sand to preserve the mold of a sandworm's toothy gaping maw, lying hidden in wait for its prey.

Profiles for 3 sizes - 100x25, 180x50, and 235x75, rather than just scaling one model up, I made 3 all maximizing the number of teeth per printer size. They all should scale up fine, but scaling down may lead to too thin walls for the teeth cavities.
