Epic War Medieval Wheeled Cannon

This wheeled Siege Artillery 3D wooden puzzle power is produced by the elastic force provided by the rubber band (which may be changed to a spring or other structure) and the cooperation between the parts replaces the need for a battery.
For the round barrel, the small wooden slats used are pieced together into the circular barrel, which provides the necessary path for the projectile.

This cool puzzle weaves history and reality together, allowing us to hear the voice of a hundred years ago. The large and heavy shape shows extraordinary momentum. A combination of gameplay and style, echoing the past and the present.
