Three years ago, Ian Davis was diagnosed with a cancer that weakens the bones. Shortly after, the engineer had an accident in his machine shop that resulted in physicians amputating four fingers on his dominant hand.
"When I was still in the hospital I started designing a prosthetic hand," Davis told KOBI News last year. "It was kind of my day job. That's what I used to maintain my sanity."
Davis's work-in-progress is an elegant feat of engineering. Coincidentally though, this isn't new maker territory for him. Long before he lost his fingers; he built a prosthetic arm as a high school science project.

After many weeks of designing and prototyping, I finally have the splay feature pretty well dialed! There were points during this process that I was getting concerned I was chasing a frivolous function, but after using it for half a day so far, I have no doubt that it was completely worth the time and effort.
