Estes Model Rocket 18mm Thrust Ring - 18mm

This is a model for a thrust ring that will fit flush on the aft end of an Estes BP motor. It is designed to replace the wraps of tape that are commonly used to create a thrust ring on the motor itself, and mimics the thrust rings commonly found on motors from Quest or Aerotech.

Printing is quick and simple. This is a one-time use model and is intended to be disposed of when the motor is spent.

To use, slip the ring onto the aft (nozzle) end of the motor and secure with a few drops of CA glue. Let it dry then insert the motor into the rocket. The motor will extend 4mm out the back of the rocket.

I also have variations for 24mm and 29mm BP motor thrust rings on my Models page, but if you need something specific, please let me know, and I will do my best to help you.

If you enjoy this model and kit, I would love for you would post a Make (with pictures and videos) as well as a Like. I also have a BuyMeACoffee page, and a donation would be appreciated if you can.

Safety Police Disclaimer:

Rocketry is a safe and rewarding hobby. With knowledge and experience, you can experience the excitement of yeeting a rocket thousands of feet into the sky. There is nothing else like it.

Having said that, you are responsible for the rockets you fly. If you build and fly one of these rockets, you should understand the NAR Safety Code and the potential risks involved with launching any rocket, especially these. They were not designed to be toys. They are real rockets that can potentially go very high and carry significant energy. This rocket is intended to be built and flown by experienced rocketeers who understand the risks and can mitigate potential issues through experience. By printing and flying this model, you do so at your own risk. You are solely liable for any unexpected results, and you agree to hold me and any manufacturer harmless from any liability. I recommend you join NAR or Tripoli, join a club, and ask lots of questions. Launching a rocket as an NAR/TRA member at a sanctioned event provides you with insurance you don't get at the park. </end of Safety Rant>
