A model of a 2-spool high bypass turbofan. I designed the whole engine from scratch with visual cues to certain existing engines.  For example, I think Rolls-Royce makes the best-looking fans, so there's some resemblance there... By the way, this model was featured on SolidSmack.
Several parts benefit from the use of custom supports. I included these supports in the parts as needed, and they are much better than a slicer's default grid-like support structures. However, certain parts (fan stator casing, for example) also have typical overhangs that still require normal supports that you'll need to apply in your slicer. All parts with the custom supports have (With Supports) at the end of the file names. If you'd rather not use these custom supports, download instead the parts with (No Supports) at the end of the file names.
The biggest parts were designed to maximize an 8x10x8 build volume. I uploaded cut-in-half versions of the biggest parts (fan casings and stand) so smaller printers can print this without…
