Incept 3D | prosthetics
The Geblin is a quick-connect device that screws into the wrist of a prosthetic arm. It contains an embedded magnet. Place your wrist next to an attachment, and it will click into place. The teeth prevent unwanted rotational movement, and if the magnetic force alone isn't enough for the task at hand (heavy lifting, etc.), you may use a metal pin to lock it into place. Each of these actions can be performed without the help of a functional hand.
