Edison is a device designed to help people with mobility and motor problems in their hands to open and close doors with keys. It facilitates holding the keys and the rotation movement of the wrist when opening the door, it can contain up to three keys, and they are easily turned out to be used.
The device becomes a handle that increases the clamping area, which facilitates the rotation of the key. The size is compact so it can be stored in the pants pocket, but firm enough to withstand the torque of the key when opening the door.
This project is open source and printed in 3D, so it can be accessed at relatively low cost, and even modified.
