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 lung cancer cross section sliced open to show a pale, lumpy tumor mass pushing through the surrounding lung. Around the growth, spongy alveolar tissue forms a fine honeycomb of pits, while branching bronchi sweep diagonally across the cut face like flattened tubes. Small vessel openings dot the lower edge, and the whole slice sits on a smooth, flat back so it rests steadily on a desk. It suits an anatomy classroom, a medical student's shelf or a pathology display where a tactile tumor specimen helps explain how cancer invades healthy tissue.
