Android finger

I modeled a simple android finger, based on my own index finger measurements, so that I could produce a realistic sized android finger.
The finger was designed to be controlled by using small steel wires, driven by small motors using a sliding worm gear for each wire. This will allow the wires to be stretched and loosened, providing linear movement.

Each finger joint will be driven by 2 wires, like a real finger uses tendons. One to pull open, and another to pull close.
The final goal is to actually produce a mold, in order to be able to inject the 3 finger sections with a termo-plastic like ABS, PS or similar.
