NEVER aim at another person or animal. DO NOT aim at yourself. I am not responsible for any injury or damage caused by the use of this model.
This ring cannon is safe to use indoors, but still uses flammable propellant and projects a small object at low speeds. Injury is unlikely, but possible if misused.
Print both the trigger and main file.
The ring cannon body must be printed with the barrel facing upward.
The trigger must be printed with its flat face downward. Use supports.
Disassemble BBQ lighter and insert piezo igniter into fitted hole.
Route wires into barrel through top and bottom holes.
Press-fit the trigger into hinge.
(Optional) Test to see is spark is present, check connections if not.
Inject butane into the chamber.
(Optional) Insert chunk of potato or other soft vegetable into barrel.
