Jet Engine, Rotable 2 Spool Rotors

I made "Jet Engine" as;
https://www.thingiverse.com/make:353656

I wanted to modify to the rotable 2 spool rotors type model.
Design points are as follows;
- Each Spool can be rotated by finger
- Original Blade_Type** are used as possible
- Aluminum Tube is used as LP Spool Shaft
- Redesign for all rotating shaft parts based on the original shape
- Front Spool Support is used with Drum-Left* and Rear Spool is supported by glued New Aft-Support-Parts*
- One piece Fan-Rotor and Spinner with support are redesigned

All STL files and assembly and installation instruction are shown in photos.
These all STL files for 40% scaled down model.

This "Remix" can be helpful to explain about the Total Jet Engine Function easely, I hope.
Thanks for viewing!
