Still waiting for it to arrive.
The Mail Box door fits perfectly and looks great. It's amazing what people can 3D print now. I really didn't want to have to find a new mail box to wrestle into the brick housing. I had some questions and he was quick to answer them. If you need a mailbox door get one from him you won't be disappointed.
