This is a Raptor 3 engine recently made by spacex on the starship. I have included print profiles for any other printers because I only have an ender 3. the model requires no glue but glue can be used to improve its durability.

Raptor 3 specs:

• Thrust: The sea-level variant of the Raptor 3 has a thrust of 280 tf. The booster/sea-level configuration is intended to achieve 330 tf.
• Specific impulse: The Raptor 3 has a specific impulse of 350s.
• Engine mass: The Raptor 3 weighs 1525 kg.
• Chamber pressure: The Raptor 3 has a chamber pressure of 350 bar.

Thanks,
