Description
This model will no longer be maintained on Thingiverse. Please see:

This remix mostly eliminates the need for supports. This is a remix of the 3D Printable High-Bypass Jet Engine by CATIAV5FTW (Chris Shakal). No supports are required from the slicer if my files with built in supports are used.
Significant changes:
Casing flanges. I split one flange off to be printed separately. This completely eliminates the need for supports when printing the casings and greatly reduced the amount of filament required. The flange is attached with epoxy or CA.
Combustion lining. Split into to two pieces so that no complex supports are necessary. Halves are glued together.
Nozzle Stator. Split into 3 parts and requires no supports. Parts are glued together.
Low pressure shaft. Split into two pieces and requires no supports. Parts are bolted together.
LPT spool. Split into 2 pieces and requires no supports. Parts are glued together.
A few of his parts are in their original format but are included with my numbering system added for convenience.
My gearmotor design will not fit unless the CV5-004 NOZZLE ASSY is replaced with TN1-004 NOZZLE ASSY from my nacelle design.
My Nacelle can be added if CV5-004 NOZZLE ASSY is replaced with TN1-004 NOZZLE ASSY. And for the nacelle I also recommend CV5-002 STATOR CASING AND FAN ASSY be replaced with TN1-002 STATOR CASING AND FAN ASSY which uses most of the same parts. Refer to the TN001 BOM for more information about adding the nacelle to this design.
Note: Make sure you place the TN1-828 SWIRL_DOME_PLATE inside the TN1-703_COMBUSTION_LINING_BODY. I see many of these models with the dome plate incorrectly placed on the end of the combustion lining body. The fuel injectors will not line up correctly with the swirl dome in the wrong position. The swirl dome plate slides in from the side in a circular motion and may not even require adhesive if it's located correctly.
Note, this model is NOT like the Rolls Royce Trent 900 as is reported by many unscrupulous Chinese vendors. The Trent 900 has 3 counter-rotating spools. This model only has 2 spools rotating in the same direction. Furthermore, This engine was not designed after any particular real jet engine.
