I've modified the 3D Printable Jet Engine made by CATIAV5FTW in order to rotate automatically using a 12V DC Motor and a Controller.
Besides the modified parts from the original one, there is a new part called "Connector" wich is practically an adaptor between the DC motor shaft and the main shaft of the JET ENGINE. If you're using other type of DC Motor, that part may not be compatible with your motor but can be easily modified for your needs.
The files that you won't have to print from the original files are next and are replaced by the files uploaded by me:
Nozzle_Cone.stl --> Nozzle_End.STL
Nozzle.stl --> nozzle_body.STL
Low_Pressure_Shaft_Aft_Rev_A.stl --> Low_Pressure_Spool_Aft.STL
What you Need:
Happy Printing! I would love to know if anyone tries my remix!
Mount it as the normal Jet Engine, but first, you have to mount the DC mottor with the wires already atached (the wires come through the holes in the nozzle cone/end) and add the "Connector" to the motor shaft.
