Stethoscope - 제작비가 2.5달러에서 5달러 사이인 오픈소스 청진기

The Stethoscope project reveals a critical tension in global health innovation: while 3D printing and open-source design can slash medical device costs from $100+ to just $2-5, the real barriers to healthcare access extend far beyond economics. The technical achievement is notable, but community feedback highlights that resource-constrained regions lack not just equipment, but infrastructure, trained professionals, and institutional trust—suggesting that true healthcare democratization requires systemic change, not merely cheaper components.
