I found the turbo MrsBecraft had put up, but the model was not very print-friendly, so i found the original model on grabcad: https://grabcad.com/library/complete-turbo-including-internal-bits-1
i changed a lot of things to make it better to print like removing some floating bolts and i also aligned the 2 housings so they are straight, and i moved the propellers out and made them bigger so its more realistic.
