Hanging bracket for a sander

Advantages of this 3D design:
Interchangeability: If you switch to a different sander (with a different guard), you don’t have to unscrew the plate from the wall. You simply print a new “front” and slide it into the same base.

No screws visible from the front: The sander doesn’t bump against the heads of the mounting screws, because they’re hidden under the slide-in element.

Safety: The sander’s weight presses the element down, making the connection even more stable.
