This thing will latch a small 2 row fuse box.
The mounting slot-hole in the door needs to be 14 mm x 12 mm and ~24 mm from the side of the door. The catch should be ~15 mm behind the door.
The parts are friction-fit but a dab of glue will be useful. The knob and the baseplate will need printing supports.
