Model Rocket Engine Bell 19mm ID

When building the Estes Hyper-Bat model rocket, the paper engine bell that came in the kit was very flimsy and creased too easily. I decided to design my own in Fusion360. I even added some "coolant spirals" to the design to simulate a real liquid rocket engine. This engine bell has an internal diameter of 19mm. This should fit around an 18mm motor mount without any modifications. Just glue it to the motor mount with the bottom being flush with the engine bell.
