UPDATE (07/06/2019) - Upgrade Package
If you want to add the Exhaust Nozzle and a small motor to spin the Fan in the front, please download the ''03_Upgrade Package.zip'' folder and see the 3rd YouTube video for instruction (watch from 1:40)

1/2 Scale model of my Jet Engine Model.
Below are Ball Bearings that I used. They are all standard parts and you can easily get them from anywhere. I got mine from RS components
Open Ball Bearings (2-off): Inside Dia 17mm, Outside Dia 35mm, Race Width 10mm
It took me around 60 hours to print this model and about 5 minutes to assemble - no super glue or fasteners are needed.
I hope you''ll enjoy making this model as I did :)
Please let me know if you have any questions.
