By building ideas, what exactly do you mean? I may be 25 hours late, but ideas might still occur.

here you go ;

You should build an airplane. Or spaceplane. I used to build a ton of those. See how many details you can include. Add an APU to an airliner? Winglets to a 737? Maybe include a little box on a 737 with a sign saying "MCAS SYSTEM (to turn off, look up MCAS in one of the manuals sitting on the shelf at the airport)".
