Locking Wall Mount For Milwaukee Packout

After posting my easy alignment Packout feet I had a request to make the same for the mounting side. I have designed one for the full size boxes and one for the half size boxes, and both have a tab to keep the boxes from falling out. The mount for the half size box in the picture was my first prototype, but the actual file will look more like the full size mount with 4 slots and multiple mounting points.
