For use with 54mm threaded forward closures from Aerotech, CTI, and Loki Research in high performance minimum-diameter rockets.
Printing and installation:
-Use a higher temperature material like PETG, Nylon, ABS, or Polycarbonate (all testing conducted with NylonX and Prusament PC-CF)
-Supports are required
-Be sure to rough the outside surface of the retainer, as well as the inside surface of the airframe tubing, with a medium-grit sandpaper before adhering with epoxy
-Use an appropriate length ¼"-20 bolt to secure the motor retainer to the casing. The single through-hole design allows for easy swapping between bolts, eyebolts, and threaded rods of different lengths for different length motors.
