Want to show us your 3D printing skills while helping out an amazing cause? You can give us the finger ;) Seriously by 3D printing parts of a prosthetic hand by EnablingTheFuture.org
Additional Information
In an effort to have meaningful 3D printer quality test sample prints, here are some design files for the 3D printable "Raptor" as found on Thingiverse: http://www.thingiverse.com/thing:476403
Once we have enough parts for a hand, we'll let you know and then send it off to http://www.EnablingTheFuture.org so they can change a life.
If you don't like the Raptor and want to help 3D print a different design, check out their entire array of prosthetics: http://enablingthefuture.org/upper-limb-prosthetics/ If you have trouble 3D printing any of these parts, let us know. We'd love to help you help us give a hand to those in need.
When you're all finished, send whatever part you've printed to our headquarters: 1595 17th Ave, San Francisco, CA 94122
