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.

An activated platelet spreads its rounded central body and throws out long spiky pseudopod arms in every direction, just as it does when blood begins to clot. Each extension is knobbed at the tip and textured with fine grooves, and shorter nubs crowd the surface between them. The radial, tentacle-like silhouette makes the cell easy to read from any angle. Bring it into a cell biology or hematology lesson, pair it with red and white blood cell models on a classroom shelf, or keep it as an odd sculptural desk piece.
