About this 3D model

I've always wanted a 3D printable robotic hand, and I know you have too.A while back I decided to take a stab at designing a wire controlled hand. I never got it right, and I'm not sure I have the background to finish it. Here are my basic parts and design files. I am posting them so other people might be inspired to work on this problem. The design files have become unwieldy so I would start from scratch.
