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 cardiomyopathy heart cutaway showing a thickened left ventricular wall around a narrowed chamber. The opened front exposes the ridged inner muscle, papillary muscles and the fine chordae strings of the mitral valve, while the aorta, pulmonary vessels and great veins rise from the top. Smooth outer surfaces contrast with the textured interior, making the disease easy to point out. It suits an anatomy or cardiology classroom, a nursing study set or a medical office display.
