"A man named Jose Delgado was so used to using a $42,000 myoelectric prosthetic hand for the last year that he didn't realize that there were other options out there. Although Delgado, born without a left hand, was able to obtain the hand via his insurance, he found that a 3D printed 'Cyborg Beast,' open source hand ,which costs just $50 to print, actually was more comfortable and performed better than the device which costs 840 times as much money."
