You may recall a man named Aaron Brown. He had created the 3D Printed Prosthetic Wolverine hand for children. Now he is at it again with a hand he called the "Wounded Soldier Hand". It is targeted toward active adults and specifically veteran of war who have lost a limb. The Wounded Soldier Hand features the ability to add on accessories and tools such as a flashlight, toothbrush, utility knife, and more. The possibilities are endless with the special track system that the hand uses. Read and see more on this at:
