Here is my FUNCTIONAL Electric Motor Driven Pratt & Whitney Jet Engine. It is very detailed. It's modeled after the F-35 F135 engine and the F-22 Raptor F119 engine. It's fully 3D printable with very few supports required. It's fully functional and cool as hell!

The Electric motor can be found on Amazon for about $25, a 12/24v power supply is required (Amazon for about $50), and a speed control (amazon about $20). It's a fairly simple setup. If you need help ask me or YouTube.

2 different nozzles are included. F-22 Raptor Vectoring Nozzle and F-35 Nozzle. The nozzles are not functional, they are static.

The Hardware folder is saved separately to not clog up the other files.

Included formats:F3DSTEPSTL - 1 file per part

The ZIP file has all formats in it.Other formats available on request.There is a separate ZIP file for only the Hardware.

I linked a video of just the intake section running with a small electric motor.Most fasteners and hardware have part numbers in the title. They are either McMaster Carr or Amazon. . There are almost 900 fasteners but they aren't all required. You can use as many as you want. I modeled the number of fasteners the real engine uses on the outer cases. You can just omit as many as you want.I'm happy to change scale or make small changes to any files, within reason. I can't rebuild entire parts.TheThe overall length is about 38with a maximum diameter of about 8. The model can be scaled to any size. The current size is about 17-18% Scale. If you print with PC/ABS the total weight is about 12 LBS. or 5.6 Kilos.YOUTUBEvery rough partial build with 3000RPM 24V motorhttps://www.youtube.com/watch?v=J-82Je3ToS8https://www.youtube.com/watch?v=S4pMDZ8olgY

3D PRINTING SETTINGS

I use 3D Xtech Carbon Fiber PLA and have very good luck with it. It's very strong and rigid, and easy to print. I print with an Ultimaker 2 Extended+0.2mm layer height or bigger. You can print finer but there isn't really a reason to. A few rotors have a small horizontal overhang that may require supports. It depends on how well your printer bridges.
