Is a Mechanic Hand but it moves like a real hand.
R2- This is a review of my previous design. I Changed the the finger joints (add hinges) and other smaller improvements.
R3- Created limits so each finger joints don't fold all the way. Also, redesign the string that connect palm to tip of fingers.
R4- Tendons are a separate model - https://www.prusaprinters.org/prints/145404-robotic-hand-toy-remix
