The Raptor Adaptor v1.0
The Raptor Adaptor v1.0 is the first step by the e-NABLE Lab at the Rochester Institute of Technology in developing a modular system for evaluating variations in prosthetic design. The modular system will facilitate comparison of new innovations, and the modularity of components will also expedite transferring new technology into working prosthetics that will be fabricated by e-NABLE volunteers.
The 3D-printed Raptor Hand can slide into the Raptor Adaptor without any modifications to the printed parts of the hand. The assembly is held together by a pair of tiny (#4 x 1/2 inch) screws that normally hold a leather palm to the hand. However, the tendons and elastics can be strung in the new modular system in innovative ways.
Then the hand assembly slides onto the PVC tubing that is used as a forearm in the conventional RIT arm. A 1/8inch hole is drilled into the tubing through a hole printed in the adaptor so that a peg or screw can securely hold the arm assembly together.
The STL file is sized for a 100% (small size for a 6-year-old child) Raptor Hand v2.2. The 28mm hole fitting the PVC pipe will have to be resized when the adaptor is scaled for larger hands (until a parametric design is created in Handmatic.)
