3d model description

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. The bolts and nuts in the joints have been replaced by bits of 1.75mm filament.
-Leave openings in the model to allow the hand to transpire
-Allow a higher degree of freedom in the wrist

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.

The model is open-source, and thus can be studied and modified to improve its performance.
