The Cyborg Beast

That's the name of a prosthetic for people who have lost fingers or never had them in the first place. A volunteer non-profit organization, E-Nable, creates prosthetic hands and fingers using 3-D printers. Unlike a normal prosthetic, the Cyborg Beast is created in about 24 hours using materials they may cost as much as $50. This is quite a contrast from a conventional prosthetic that takes weeks or months to build and costs in the thousands. 

The Beast does not look like a typical prosthetic. It's colorful and looks like a limb from a Transformer. It is not made to be hidden; they can have a variety of eye-catching fluorescent colors, or even glow in the dark. There are no patents, all designs are in the public domain.
