The Open Prosthetics Project

Once in a while you find something really worthwhile you just have to share. The Open Prosthetics Project takes the idea of Open Source beyond software. As stated on the website

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.

Now that says it all. To make the project as accessible as possible they've chosen Alibre Design Xpress as their 3D parametric CAD software.
