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.

Twin lobes of a chloride channel protein rise through a thick slab of lipid bilayer in this cell membrane model. The dimer has a soft, rounded, lumpy surface, with a central cleft running between its two halves and lower lobes hanging beneath the membrane. Packed spherical heads line both faces of the bilayer, with wavy tails between them visible on the cut sides. A clear way to show ion channels and bioelectric signaling in a biology classroom or on a science desk.
