An engineering student, a robotics lover, Thingiverse user armjunkie has designed and created this amazing Robotic Hand using a 3D printer. This time the Robotic Hand is updated to version 3, comparing to the version 2, it requires less non-printable hardware and less plastic parts to print. It shortens the printing time and you will only need to lightly sand the joints to get a smooth rotation along the axis. Each joint in each finger is controlled with fishing line. Totally you need to print out 32 3D printed plastic parts, plus 23 M3x12 screws, 23 M3 hex nuts, 5 strands of fishing line, between 15 to 45 dental rubber bands(to tension each joint in each finger).

Even though it is just a prototype and still in building process, it is a fun to watch the opening and closing motions from the fingers. According to armjunkie, you can customize the number of rubber bands to control the speed of the snap, and also to adjust which joint should be folded first by change the numbers of rubber bands at joints. 

armjunkie is planning a special re-design of the thumb out in Summer 2012.
