3D model description
This is a water rocket launcher, which can be fully 3D printed using using the 19x2mm TPU seal and the Inlet_Metric, or use store bought O-rings.
Here's some footage of it in action:
19mm (inner diameter) 2mm cross section
3/4" (inner diameter) 1/16" cross section
To adjust the release tightness, you can scale the printable O-ring or the pin, as pictured in the gallery.
There's two options for fixing the launcher in place:
Mount_Heavy_Duty is fixed directly to something solid (wood etc.)
Mount and Leg_Peg for removable use, to ground or sand.
Assembly instructions below. All parts should be printed with 100% infill and with 0.2 layer height for optimal clearance between parts.
1 Print all parts and get the hardware if you decide to use the actual valves and O-Rings
2 Insert the O-Ring to the Inlet
3 Glue the Bottle Adapter to an empty bottle, or print a rocket
4 Attach a cord to the Pin and connect the pump to the Inlet
5 Fill the rocket with water, and combine it with the Inlet and insert the Pin over them
6 Insert the assembly to the Mount, which should be secured in place
7 Pump to desired pressure
8 Launch by pulling the Pin

Remember, this uses high pressures, so adult supervision and common sense is a must. The maximum pressure tested so far has been 10 bar (145psi) with the PVC Rocket
More rocketry coming soon, so stick around!
Toss a like, post a make and maybe follow

3D printing settings
To prevent leaks, use random location for the layer change. The Z seam is the main reason for leaky prints under pressure. The Leg_Peg is recommended to have supports to improve stability.
