The Door Keeper: A Device to Prevent Doors From Self-Closing. This clever device features a two-part design that relies on an M5 screw for stability. The screw is tapped into the outer part, creating a secure connection between the two components and providing friction to keep the door from closing on its own. The inner component is held in place by being pressed onto a folded metal piece attached to the metal window frame. However, it's essential to note that support may be required during printing, as depicted in the accompanying image.
