Remixed Thruster

I want the inside of the thrusters to be smooth and also wanted a location to mount a large RGB LED neopixel ring. I used the model by Drokle and referenced other mages of the rocket pack to design a thruster bottom that i like. This is compatible with the other parts of the Drokle model. Working on sanding and priming the first sample i printed, but it fits well so i am uploading the files.
