venturi burner casting mold

this is a split mold of a venturi burner i designed for casting. if you want to build a venturi burner, this is your mold. i have not tested it, nor printed it. i am confident though it will work.
i suggest you cast it in aluminum, and tap it for the nozzle in any size you see fit. you may want to enlarge the hole, depends on the nozzle. later, i will add a knob that will open and close the air supply by screwing it further or closer to the flame end of the burner. i hope you like it. have fun
