The Gripper Thumb Hand is a voluntary opening (normally closed) Terminal Device (TD) for a prosthetic arm compatible with the Modular Training Arm Framework.    One moving part (the thumb).

It is printed flat and then thermoformed so that the 4 fingers are fixed in a flexed grip. The thumb pivots at the proximal end and is flexed under power of an elastic ring in order to contact the first two fingers in a “three-jawed chuck” grip. The grip is opened by a Bowden cable that is pulled by an elbow or shoulder action.
