3D printing a golf club compatible with prostheses
Relearning an old sport or starting a new one can be difficult for amputees. Besides the obvious physical aspects, custom prostheses or adapters may need to be fabricated and fitted, which can be very expensive. With the power of 3D printing and a bit of machining, [Ian Davis] was able to build a custom-made prosthetic golf club to bring a quadruple amputee back to the greens.
The recipient of this prosthesis lost both hands above the wrists, so [Ian] had to find a mechanism that could hold the club and mimic wrist motion throughout the swing. He was able to achieve this movement with a simple four-plate hinge for each arm. For optimal ergonomics, [Ian] also added dual axis adjustment, with only one bolt needing to be loosened per axis. A standard golf club can be used and is clamped in the printed holders.
Machined prosthetic sockets were used to allow quick connection to the user’s existing prosthetic forearms. Theoretically, this should also allow him to switch clubs without undue hassle. [Ian]himself an amputee, used his engineering skills to build a series of prosthetic hands and even a custom controller mod to return to gaming with fewer fleshy fingers.
