-This works because the inner hole is 1 mm
-Connect the finger sections using M3-16 screws and M3 nuts.
-Connect the hands to the fingers using the same method.

-Tie knots on the end of each of all the strings (see second to last image)
-[Thread the string through the fingertips and tie a second knot (see last image)
-Thread the string through each finger section and through the palm of the hand)]
-Repeat for each finger.
-Cut a hole out of the side of the PVC pipe.
-Mount the hand on the top of the PVC pipe and run the strings down the pipe and out the hole.
-Thread the string guide through each string and glue it onto the inner pipe (to keep the string form tangling).
-Slide "String_Organizer" up the pipe onto the wedge that was cut out.
