NU has designed a free, prosthetic, 3d-printed hand for kids who need one. 52,000 downloads. Cost to print: about $50

From KIOS's Deborah (Van Fleet) Newcombe:

    A group of researchers from four University of Nebraska campuses has received a two-year grant to collaborate on the Next Generation 3D printer prostheses for children.
     ...The grant’s lead investigator, Dr. Jorge Zuniga, an assistant professor of biomechanics at UNO, says up to 58% of children missing a hand or upper limb are not fitted for a prosthetic device, or they get one and reject it.
     In response to this need, Zuniga developed the Cyborg Beast, an open-source 3D prosthetic hand, which can be constructed for about $50.00 and has been downloaded over 52,000 times.
     ...These devices are made out of plastic, so they are very light. So they don’t require -- like a prosthetic arm -- doesn’t require a harness. We figured out if you make a device that they can put on themselves, they will be more likely to use it.”
     Zuniga says one of the goals for this grant is to develop electronic, switch-activated versions of their prostheses...
