A very loud cap gun that uses standard 209 shotgun primers!

As everyone who grew up with cap guns knows, they don't make them like they used to. Modern cap guns are absolute crap, and it has become increasingly hard to find caps for them. Why not print a much nicer (and more powerful) cap gun for your little tyke?!*
- Protective goggles are highly recommended, as 209 shotgun primers are extremely powerful and could potentially cause the gun to explode. This gun prints with a partially obstructed barrel, making it impossible to fire projectiles. Please do not try to modify it for any other purpose, as doing so could be dangerous and/or illegal.
