Vacuum version of the Raptor Engine from SpaceX Starship program. I've been following Starship for some years now, and I've always wanted a Raptor Engine to display. I could not find any on Printables or Thingiverse, so I decided to give it a shot and make my own in Fusion. I used a few reference images, but I had to take some creative liberties to make the model more printer friendly.

Unfortunately, there is no way to print without supports, but I have the settings pretty dialed in for PLA, and they come off with ease using pliers. 

Please leave makes and suggestions. 

*****WARNING*****

I recommend adjusting the model scale before going big, this is not an easy print. One option may be to slice the model about 70% of the way up the nozzle and printing the two pieces separately.
