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 rod-shaped bacterium is cut open along its side to show the coiled nucleoid DNA tangled through the middle of the cell. Round ribosomes are scattered throughout the interior, short pili bristle all over the outer surface, and three long wavy flagella trail from one end. The layered cell envelope is visible along the cut edge. Realistic and full of texture, it makes a strong teaching model for prokaryotic cells in a biology class, a microbiology lab display or a striking science desk piece.
