Abstract
- The Stethoscope is one of the most basic medical tools. It allows a trained medical professional to diagnose issues with the heart and lungs. Stethoscopes come in a range of prices and quality, but all are breakable. This Stethoscope only requires some surgical tubing or similar airtight tubing and 3D printed parts.
Bill of Materials
- BOM
- 3D printer
- Filament

Based on the developmental needs addressed (e.g. food, heat, electricity, clean water, health care, etc.) be sure to label your device in the proper categories e.g. use [[Category:Water]]. Be sure to categorize your device so that it will be easy to find – for example “Low voltage connection basics” is categorized in [[Category:How tos]] [[Category:Electricity]] [[Category:Electric lighting]].
