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.

Early human embryo inside its amniotic sac, sculpted as a rounded mass with the tiny curled embryo pressed against the membrane. Limb buds, a small eye spot and the umbilical stalk can be picked out near the folded body, while veins branch across the sac's smooth surface and a rough, lobed cluster of chorionic tissue gathers at one side. It brings the first weeks of development into a form students can hold, suited to biology and embryology lessons, health classrooms and science display shelves.
