Water rocket launcher

This is version 3 of the water rocket launcher. I recommend printing with 5 walls at 25% infill for best results.I got my valves at ace hardware but most tires valves should work. i also use Teflon tape around the threaded part.IMORTANT NOTE: Make sure you have the correct valve by checking with the thread part before printing as youcould waste a lot of plastic if you print the whole thing just to realize that you don't have the correct hardware. Thefit when you put the bottle onto the launch pad will be snug you may have to push hard
