WATER ROCKET 3D print model

The water rocket is made from a plastic bottle.

...I'll give you the parts you need to stabilize your rocket, the nose and the ailerons.

The nose has a hole for hanging a parachute.

The parachute is made of thin plastic and sewing thread. A paper cone is added on top to hold it in place during take-off.

The version developed here uses a half-litre bottle ( 63 mm diameter) of mineral water (Saguaro on sale at LIDL).

To use it on a larger bottle you can use the scale function of your slicer.

For the rocket part, I aim for a tap nose on the bottle after removing the whole cap.

Afterwards, the seal is sealed with DIY tape.

The pressurization is ensured by an air pump (I use an inflator of about 3 bars) to connect and release the rocket, a quick coupling fulfills this function.

The bottle contains about 12 cl of water and the pressure of the contained air ejects the water, which propels the rocket.

given the low pressure, I activate the quick-release coupling to launch the rocket...

I recommend vigilance and the wearing of protective glasses because in this configuration the bottle is propelled at a height of 10 meters.
