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.

Sliced open lengthwise, this wheat grain cutaway shows the seed from the outer bran layers to the starchy endosperm and the embryo germ tucked at its base. Layered skins wrap the grain in thin bands, the endosperm fills the middle with a grainy, floury texture, and a tuft of brush hairs crowns the tip. Shaped like a real kernel and free of any base, it suits a botany lesson on seed anatomy, a nutrition class explaining whole grains, or a shelf of plant science models.
