This is an External Extensor Exoskeleton that is used for rehabilitation of the extensor tendons of the hand. Adjust the design to fit the patients hand, and adjust the thickness/infill/material for more of less flexibility. After printing with TPU of other flexible filament, simply attach the bands and put it on the back of the patients hand. This external tendon will make it easier to open the hand.
