A simple 3d print of a holder to screw on your mail box post or anywhere else to hold a small American flag. It is about 2.75 inches long with a 3/8 tube for the flag dow rod. The tube is made larger that the dow rod because when the dow rod gets wet it swells and can not be pulled out. There is also a small hole in the bottom of the tube to let any rain water run out. It requires 4 small screws for mounting.
