3D printed prosthetic hand

This prosthesis has been designed to help those people with missing fingers.

It has been modelled keeping in mind the following principles:

Keep the number of printed parts as low as possible. -Keep the assembly process as simple as possible.
Use the least possible amount of non-printable parts. In this new model, you can choose how to join fingers, using screws (2M), axes wire, or filament printer. Leave openings in the model to allow the hand to transpire.
The previous model had another hand rotation system on the wrist, had more freedom. On this occasion I have modified the movement of the wrist using the fantastic idea of a union that uses hand "Flexy-hand v2": http://www.thingiverse.com/thing:380665
I have also modified the system of tensioning the strings. It is safer than before and takes up less space.
I have included a version without thumb for those who have their own finger.

The fingers flex when they are pulled by strings, such as fishing line, and extend automatically with the help of elastic cord. A fabric strap with velcro is needed to secure the prosthesis to the arm.

You can download the original file blender, and thus can be studied and modified to improve its performance.

I hope to be successful with modifications. Thank you very much to " Africa Directo" http://www.africadirecto.org/ for suggesting changes and help to improve the model.

Is based on my previous design: http://www.thingiverse.com/thing:1095104
