Hello

[ACHris]

Hey guys!
My name is Chris from Glendale, CA. I recently got into water rocketry. I was asked to design a dual rocket launch system, for a STEM program. Included below is what I came up with: It has two check valves to control the amount of water in each bottle, and it has 2 one-way valves which controls the air flow. The launch bases, guides, and fixtures are all 3-D printed. It worked great! Now I'm more interested in building the rockets!
Thanks
-Chris

That's a great looking launch system! Is that ABS?

Yes, it's ABS. Some of the areas with less stress have a sparse matrix compared to the dense high stress areas.
I have SW and STL files if away one is interested.
