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.

Spiky and alive with motion, this activated platelet model shows a blood cell switching into clotting mode. Long tapering pseudopods reach out in every direction from a lumpy central body, some ending in rounded knobs, while the surface is pitted with granules, bumps and small channel openings of the open canalicular system. The rough organic texture gives it a real sense of a cell at work. A memorable teaching piece for hematology and cell biology lessons, or a bold display on a science shelf.
