This nerf barrel adapter with a hole to fit a length of 1/2 inch PVC pipe. Can be used to make the A-280CFE from Star Wars Rogue One. Print it with the largest flat side down, the lugs should be at the top. There are two files, one with meshmixer supports for the lugs and one without. The file with the supports is in the correct orientation for printing but the other file should be flipped upside down.
