The Open Prosthetics Project is an open design effort, dedicated to public domain prosthetics "The Open Prosthetics Project is producing useful innovations in the field of prosthetics and giving the designs away for free. By substituting public good for profits we believe that we can generate far more societal benefit than if we commercialized and sold our ideas. This project is an open source collaboration between users, designers and funders with the goal of making our creations freely available for anyone to use and build upon."
