Fritzbox Wall Mount 2-Piece

I have created a wall mount suitable for a Fritzbox 5590 or 7590. The internal dimensions are W: 305mm H: 230mm D: 68mm, or slightly larger. It is a modular mount that, despite its size, can be printed with an A1 or similarly sized printers. The two parts are designed using the tongue and groove principle, making it easier to glue them together. The box is patterned on the front and completely enclosed, as are the sides. The top of the mount is completely open, and the bottom is designed with cooling fins and an opening for cables (wires). The back panel is designed to be completely open, allowing existing sockets or other unevenness to disappear behind it, as can be seen in the last picture. Since the box was designed for a hallway where small children might be running around and there's a lot of activity, I designed the suspension in a U-shape so that the item doesn't immediately come off the wall.
