3D model description

I used a bottle of Salvetat to make this rocket. Of course, you will be able to use other kinds of bottles by resizing the parts.

The flat aileron support is designed for a diameter of 66 mm (hollow of the bottle) and the nose support is designed for a diameter of 78 mm.

I advise you to put a few drops of cyanoacrylate glue between the support of the nose and the bottle, after tightening it.

The parachute is cut out of a garbage bag with a side of about 50 cm, cut out an octagon and attach a string of about 40 cm at each end. connect 4 strings on one side together and attach them to one of the holes of the nose support with a small piece of string, do the same for the other 4 strings in the opposite hole. the nose string must be about 20 cm longer than the parachute string and is connected in the outer hole of the nose support above the 2 screws.

You will need 8 m3 screws of about 10 mm.

I cut a valve from an old mountainbike inner tube and pushed it into a cork cut by about half and pre-drilled with a diameter slightly smaller than the valve.

The pump support is screwed on a wooden board to make the shooting stand. You may need to modify this part depending on the pump you will be using.

Do not hesitate to send me a message with your email address for further information.

Operate the rocket in an open area!

Fill the water bottle about half full.
