🩺 You can 3D print a working stethoscope for just 2-5 dollars.

GliaX (Swiss non-profit, working with ETH Zurich) released open-source design files for a functional stethoscope. Total material cost: just 2-5 dollars.

It is peer-reviewed and validated against the Littmann Cardiology III, a clinical gold standard. Not just a concept — real, verified performance.

STL files and assembly video are freely available on GitHub.
