24mm to 29mm Model Rocket Motor Adapter

Adapter to use 24mm model rocket motors in a 29mm motor mount. Designed for use with reloadable casings, or single use motors, that have a thrust ring. Easy print, nothing fancy, the internal step in the main casing body is chamfered to help with overhang print quality. Does NOT work with Estes black powder 29mm motors with the cardboard cases.

Tested to fit with Aerotech or CTI 24mm cases, using an Estes threaded motor retainer. Other brands may not have enough thread depth. Printed on
