Water rocket toy

Description
This is a water rocket I made for my son. It is designed to be used with a standard bottle with 28mm diameter, 1881 standard. In order to launch the rocket you will need:
- Plastic bottle (0,5l - 1,5l with a 1881 28mm bottle cap, standard in the EU)
- Air pump
- Ball attachement for the air pump (looks like a needle)
- Rubber bottle plug for wine bottles (optional if you dont print the plug)
The fins are attached to the central hub, which is screwed on to the bottle neck. Push the ball attachement for the pump through the plug (print it in TPU). Fill the bottle with water up to about ⅓. Insert the plug in the bottle (the deeper it is inserted, the higher the rocket will fly) and place the rocket on flat ground where it will not tip over. Connect the air line and move the pump as far as possible from the rocket. Give it a couple of pumps and see the rocket fly. I suggest you print it in ASA, as otherwise the fins can crack.
