Jam Jar Pulse Jet Concrete Mold

I've been playing around with jam jar pulse jets and thought it might be interesting to combine a jam jar pulse jet with a tesla valve. The uploaded files are different 3d printable molds you can use to cast a plaster or concrete model for testing. The design combines a reynst jam jar with the circular tesla valve by Bret. He did a nice job on the circular tesla valve design.For fuel pour 5 to 10 ml of methanol or heat de-icer into the bottom and light. Short video showing steps to make a functional jam jar pulse jet from a 3d print.Changes 4/19 ver_4updated the jam jar to a design from later reynst geometry4/17 ver_3changed tesla valve intake runners to round pipe4/16 ver_2reduced the intake area to match the exhaust nozle areaprint with exaust nozzle on build plateno mold cover. glue to bottom of pringles can or something and fill to top of model with concrete4/15 ver _1Increased the distance between the mold cover and the jam jar for a thicker shell.Added radius to the air intake to make mold stronger when peeling off the build plateIf you enjoyed this project make sure to check out my griggs cavitation video.
