38mm Motor Retainer
This is a screw-style retainer for 38mm high power rocket motors, inspired by similar retainers from AeroPack and Apogee. It securely holds a 38mm rocket motor in the mount so that it is not popped out by the rocket's ejection charge, and allows for easy, fast, and tool-free installation and removal of motors.
How to Use
Glue the side of the base with little grooves to the protruding end of your rocket's motor mount using JB Weld High Heat or similar high-temp epoxy
Note - make sure that when designing/building your rocket you leave at least 1 cm of motor mount tube protruding past the aft centering ring to leave room for the retainer to slide on
Insert the motor all the way until the thrust ring fits into the base
Screw the cap on firmly
Aim the pointy end at the sky and launch!
It is recommended to print this part with 100% infill using a strong engineering filament such as ABS, ASA, PETG, PC, or Nylon, as it can take a lot of force from motor ejection charges.
