The Gun is not included in the files and not by me. You can find the gun in makerworld here>> https://makerworld.com/en/models/63161#profileId-71793 The target includes cups, a ledge and a hook all worth different points as in the print to make a game of it. The little hooks in the back of the cups are there to try and keep the rubber bands from bouncing back out and it works well. It works best with longer, thinner rubber bands from about 15 feet away.
