This thing is a water rocket, which can be fully 3D printed using using the 19x2mm TPU seal and the Inlet_Metric, or use store bought O-rings, sizes below:

Inlet_Metric O-ring
19mm (inner diameter) 2mm cross section
Inlet_Imperial O-Ring
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…
