So, I heard NASA is looking for contractors to take Things to space, so why not print your own rocket launch system!
For more rocketry, check the whole collection here
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 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 9 Houston we have lift off!
13 Houston, we have a problem
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
Toss a like, post a make and maybe follow me over at the IG's
