We just fixed downloads: every STL now comes straight from fast, reliable storage, saved under its own name, we're making 10,000 STL files and dozens of new tools, so things might break. We'll fix them ASAP.

Pincers raised high, this crayfish faces you head-on in a defensive stance, its big claws studded with rounded bumps and lined with toothed edges. Long antennae sweep up and out, the domed carapace shows clear seams, and slender jointed walking legs splay out to brace the body, with a fanned tail visible behind. Lifelike anatomy makes it a strong freshwater crustacean model for biology lessons, and a bold, eye-catching piece for an aquarium fan's display shelf.
