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 The bolts and nuts in the joints have been replaced by bits of 1.75mm filament.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.
