An e-NABLE Volunteer Builds Prosthetic Hand for Recipient with Missing Fingers. The Modified Hand Features a Working Thumb and Improved Design. A recipient of an e-NABLE prosthetic hand had two missing fingers, but a fully functional thumb. To address this challenge, a volunteer created a modified Raptor hand using 3D printing technology. The initial design proved too bulky for the recipient's hand, prompting a quick revision in Tinkercad. The revised Raptor Hand maintains the same width and height as the original model, but its length is extended by 30% to accommodate the recipient's needs. Notably, the holes for hinge pins remain unchanged, ensuring seamless integration with existing components. The thumb opening has been enlarged from approximately 27mm to 46mm, providing a more comfortable fit. To enhance user experience, the volunteer designed a custom palm cushion based on the Raptor Adaptor model. This addition provides additional support and comfort for the recipient's hand, further improving the overall functionality of the prosthetic device.
