Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4847635.

A simplified Raptor Engine, easy to print in one part with a FDM-Printer. Print it upside-down, to avoid the aggressive overhangs on the pipes. It may need atleast a Brimm and Supports starting from the Print-Base. I would not scale it down, the pipes are already pretty thin.

Don't expect it to be super detailed with matching all the details of a real raptor engine, it's a simplified version and changes to be better printable.

The actual model comes from MartianDays! Dope account. He has many other rocket designs for CC. So in terms of Attribution, attribute him. :) I only changed the model a bit to make it easier printable.
