thingiverse

This vacant space within the ring and shaft can be filled with aluminum foil or other conductive materials to enable the ring to function as a capacitive touch device when worn. Wear it continuously and use it for pressing buttons at ATMs, elevators, or signing names on cash registers. It's particularly practical when washing your hands is not frequent, allowing you to disinfect the tip after each use. This version boasts an internal diameter of 20.5mm, accommodating most average-sized hands. A smaller version will also be available for those who require it.
