Double barrel hitter box

You can print the lid at its original size since it matches the dimensions of the receiver. Alternatively, reduce the scale by about 3% and trim the excess material afterwards, or simply scale it down to 97% vertically as I did. Either method worked perfectly for me. The lid features a recessed area that snaps into place when you add springs, securing the lid firmly in position until you release it by pulling down on the spring-loaded handles through a small slot located on the side of the receiver.
