USPS Collection Box (Blue Box) Mail Holder Using a Vintage PO Box Door

Mini United States Postal Service (USPS) Standard Collection Box Receptacle (Blue Box) that uses a vintage Post Office (PO) Box Door.  Can be used as a mail holder, change bank, or display piece.

The back piece is not completely symmetrical.  The side with slightly longer distances to the notches goes to the top.  When it is correctly placed in, the bottom of the back should be flush with the bottom of the sides.

The foot locks are something I was considering using, but chose not to print for my model.

I stuck all the pieces together with a small amount of super glue.
