Prosthetic Claw/Hand

Doing a prototype replacement hand for a guy that somehow has no digits, just one thumb metacarpal which could give some power because the wrist operated hands don't seem to be much use for finer functions like squeezing the toothpaste, opening a popsicle or sewing etc.
This is the first one and hopefully it can print as one piece and be functionable right off the printer. Print in shown orientation with support.
Here's the Orchard dev tree if anyone gets some incentive, blah blah blah
