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.

A voltage-gated channel is cut away to show sensor helices pulling the central pore gate open inside a slab of lipid bilayer. The membrane on both sides is sculpted as rows of round lipid heads with wavy tails between them, and the channel's halves part around a hollow pore lined with stacked helical coils. The cross section makes the opening mechanism easy to follow. Use this ion channel cutaway in neuroscience or cell biology lessons on nerve signals, or keep it as a teaching display piece.
