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.

An orangutan skeleton stands hunched forward with its very long arms reaching nearly to the ground. Curved finger bones, a full rib cage, a broad pelvis and short legs show the proportions that suit life in the trees, while the skull has the heavy brow and jutting jaw of a great ape. Bone joints are clearly defined from shoulder to toe. It makes an excellent anatomy classroom model for comparing primates and a curious display piece for a natural history shelf.
