Nerf Alpha Trooper barrel attachment

This is a mod for the Nerf N-Strike and N-Strike Elite Alpha Trooper. It allows for the attachment of most Nerf barrel extensions. It is recommended that it is printed at 100% size as it has tolerances designed into it, though your printer may be accurate enough that it needs to be made smaller. It should be glued into place, like shown in the first picture. I recommend hot glue, as it is removable, but most glues will probably work. You will need to print one of each part, and I have included the .step file of the entire design for editing.
