When I originally printed this model, the smaller angled parts of the nacelles were easily broken off due to the interface between the parts being so thin. I edited the nacelles to provide a sturdier connection.
I then designed the display stand so that the model is supported by sliding it backwards in to the stand. It is held in place by the lip on the back side of the model, allowing it to be easily removed from and returned to the base.
You may need to slightly widen the groove on the stand that holds the model, depending on the resolution you use and your printer or slicer's tolerances. I used an Xacto knife and had it fitting nicely in a couple of minutes.
The pictured model was scaled up to180% and turned out pretty nicely after cleaning up the supports.
