3D Printable Jet Engine

A cutaway model of a 2-spool high bypass turbofan. I designed the whole engine from scratch with cues to certain existing engines. For example, I think Rolls-Royce makes the best-looking fans, so there's some resemblance there... Since originally uploading this in 2016, the popularity of this model has grown far beyond expectations. The model has appeared in numerous publications, additive manufacturing expos/conferences, and is (for better or worse) being made and sold by a number of 3rd parties. However, rest assured that this is one of the official sources for this model. A bunch of remixes of this engine are out there, mostly in Thingiverse at the moment, if you are so inclined. Many parts don't need supports, but certain parts (fan stator casing, for example) have typical overhangs that still require normal supports that you'll need to apply in your slicer. Each part was designed with a specific printing orientation in mind. Due to the concentric fit of many of the components, the order that parts are assembled is very important. I uploaded a diagram with labels to all parts for reference. Pay special attention to the orientation of the compressor stages so as not to install them backwards. Multiple assembly videos for this model are available on YouTube, just search for "3d printable jet engine assembly guide". Please refer to the Bill of Materials (BOM) to keep track of what to print. ====================================================================== The required fasteners (screws, washers, and nuts) and ball bearings are listed below.
