I'm new to Fusion360, but this stand does what it's supposed to do, so I'm happy with it.
No supports needed for the main part, just for the snap-adapter that can be glued on to the stand afterwards (so you can choose the angle in which the Falcon will stand on it).

I needed some sanding or cutting on 2-3 edges of the adapter to get in in place.
Works with the Fillenium Falcon @100% size.
