I managed to get Dinah's hand bones printed out in ABS on my Anet A8 3d printer the past couple days. I also cleaned up the prints, removed the supports, and sanded down high points. They are ready for attaching them together with cloth tape which will act as artificial ligaments.

You'll note I fused the ulna and radius bones together to use as a rotational joint for the wrist to function like a human wrist. The actual pronation and supination of the forearm though will happen by way of the steel skeleton having a rotating pivot point unlike the human body where the radius rotates and twists over the ulna in a criss cross.

Note: in this photo the middle finger is missing the distal tip which I was reprinting as the time of this photo.
