Water Rockets

thingiverse

A collection of water rocket components designed specifically for 1.25L soft drink bottles, such as Kirks brand in Australia due to their straight-sided taper. ABS printing is recommended over PLA as the latter may break on impact. These rockets do not require parachutes. Two types of nose cones are available; a pointy one for easier Artinel printing and any other flexible material. Traditional and circular fins are included, with circular fins being more durable and user-friendly. The fins attach to the bottle using wooden skewers as mounts. A rotator mount is also provided for increased stability in flight, although circular fins already offer good stability. Properly adjusted skewers can result in a gentle tumbling descent.
