This is in addition to the CATIAV5FTW High Bypass Jet Engine fan (High Bypass Jet Engine Fan by Catiav5ftw - Thingiverse). After I printed it and hung it up, I found that something was missing. So I designed a cowling. It has the characteristic shape of the one of the Boeing 737-8.
The six parts are simply glued together, certainly not the nicest solution, but it works. To mount the turbine blade on the wall, I constructed an axis and an adapter that is glued into the disk.
The ball bearings have the dimensions 12x28x8.
Hope you will enjoy printing it.
