Spinning Jet Engine Model

Turbofan jet engine model, where the middle high pressure stages spin faster than the other stages to replicate the real workings of a jet engine. This is done through the use of a planetary gear box which rotates the central sections at 3x the speed of the outer sections . All stages rotate using 3D printed bearings which connect the blades to the containers centrally, which allow the blades to spin without clipping the containers. The only non 3D printed thing is a 9mm wooden dowel, which is required to be fed through all sections to provide a strong structure.
