thingiverse

This project involves using goblin shotgun shells. To begin, print two pins. Next, obtain six 32 screws and springs for these pins. Attach the pins and springs to the old barrel and handles. After that, insert them properly. Then, assemble everything with screws. Also, add a small screw about a quarter of an inch from the back of the barrel between the barrels. Finally, cut a small piece of metal to reach from the hole in the middle of the handle to the screw.
