Nick Brookins, media services engineer at Akamai Technologies was left with amputed finger in the hospital after a motorcycle accident in the mountains near San Diego. Inspired by the original Owen Replacement Finger design, he then developed his own 3D Printed Prosthetic called the Knick Finger from scratch using OpenScad code and printing it on his Printrbot Simple. The 3D Printed Knick Finger also protects his very sensitive nerve endings and reduces pain, he stated.
