About this 3D model

Snow Bullet Mold for 3" Air Cannon barrel. Use a small section of your cannon barrel to form the outer case of the mold that fits over the nose code mold you print out. Nose cone mold and Plate both have holes for 1/4" hex head bolt so you can attach them to a block of wood as a base. http://youtu.be/hFRuMYJ_OxE More on the cannon this is made for: http://www.siege-engine.com/AirCannonJr.shtml
