I attempted this lengthy Thinigiverse item, a Boeing 737:
I have a Creality-CR10S and can provide the settings for this print. One major detail for the success of this print is the engine struts or the mounting component for mounting the engines to the wing. The left side strut detail did not print, however the, the right engine mount did print. See attached.
I think this is a bug that the sclicer didn't include this model feature.
