Mini Cannon

thingiverse

You'll need to build a mini cannon that shoots, requiring four screws to secure the barrel onto the base and two more to hold the barrel insert in place. To prepare, get a drill bit sized to match the wick of the 9 mm shell, then insert the barrel into the holder and mark the hole before drilling it out. For added stability, use the two screws to press down on the 9 mm shell, ensuring it's seated properly. When it comes to ammo, consider using BBS for a shotgun-like effect or 9 mm balls for a more precise shot. Always verify your local laws before firing and enjoy the experience!
