The file 'Water Rocket (Bottle Rocket) Adapter With Fins 3D Printer Model' is (stl) file type, size is 302.2KB.
This is a derivative of my 2 Liter bottle to 1/4 NPT adapter with reasonably sturdy little fins. The adapter is designed to let you quickly turn an ordinary house hold pop (soda) bottle into a projectile by adding water and air pressure. the 1/4 NPT quick disconnect gives you a simple and easy way to add air pressure and also works as a launch mechanism when you release the collar.
