This adjustable grip has been designed to allow the user to perform a variety of everyday tasks including but not limited to: brushing one’s teeth, combing one’s hair, writing with a pencil, and other tasks that involve holding a small (cylindrical is optimal) object. Instead of making task-specific hands for each one of the tasks as we initially planned, we decided to streamline the design and make it more convenient for the user by having a “catch-all” design.
The 3-pronged claw design in the STL provides the structure of the hand, however, we designed the hand to also accommodate a Velcro strip as the moving/tightening mechanism. In the STL you will find that 1 pronged piece can move freely in the track in the 2 pronged piece. A 1 inch wide Velcro strip should be attached to the bottom of the 1 pronged piece so that it fits in the slot behind the track the 1 pronged piece slides through. The other side of the Velcro (hooks) should be adhered to the Python wrist. This way, the user can pull the Velcro through the slot and stick it to the wrist to tighten the claw accordingly to the object that they are grasping. With the claw tightened, users can then perform the task and simply un-velcro the strip when they are done.
