Snow Bullet Mold

thingiverse

Create a Snow Bullet Mold for a 3" Air Cannon barrel by fitting a barrel cut-off over a printed nose cone mold. Both the nose cone mold and plate include holes for attaching a 1/4" hex head bolt to a wooden base. For cannons without a 3" PVC pipe barrel, specify its inner diameter in the openscad files. Secure the molds with ski-wax on the inside of the nose-cone mold and use a 1/4" bolt to fasten them to a block of wood or other solid material. Fill the mold with snow, pack it using a ramrod, then remove the barrel section and push out the snow bullet.
