This uses the existing screw location and screws to add a little bracket for wall mounting. Print this thing, take the screws out of the back of the charger, then re install them with the bracket.
You need to print this with the open (back) side of the screw hanger facing up. This leaves the open side of where you mount this to the charger hanging up in space. The print quality of the surfaces where this mounts to the charger is pretty crappy but it still works great. If you print with supports, it'll be cosmetically better and functionally worse.
