Model Rocket

These are model rocket modular parts that are compatible with Estes BT-50 rocket (0.98 inch diameter) tubes. In short:

rocket = stage + tube + nose

multi stage rocket = booster + stage + tube + nose

rocket with payload = stage + tube + payload + nose (see https://www.thingiverse.com/thing:7067681)

IMPORTANT: See https://www.thingiverse.com/thing:7056020 for more parts, with more fin, nose cone and tube options, including reinforced tubes. These parts are all interchangeable.

First you select a 'stage' (holds a standard engine, has 3 fins and a launch lug) and optionally (for a multistage rocket) a 'booster' section (holds a booster engine, has 3 fins and a launch lug and attaches to a stage section) and nose cone options, and assemble with a shock cord (e.g. kevlar thread) and parachute. You then use a tube of the desired height (either printed or cardboard) to connect to the nose and stage sections. Booster sections (if used) just slide underneath into the stage section. Both
