18/24mm Motor Adapter

thingiverse

This is a simple adapter for using 18mm motors in a 24mm mount. It includes a ring at the rear to hold the motor in during chute ejection, no friction fit required, as well as a thrust ring on the outside of the adapter, just in case you designed your rocket without a thrust ring in the motor mount. Print 2 - the included STL is only half of the adapter.
