Boffin1:
I have spent many hours drawing this high tech engineering drawing on a napkin( I don't think you can see the wine stains on the scan .)
So how many bottles of wine did you drink, exactly?
I think it would be quite a challenge engineering it with such a long nozzle; the plastic needs to be hottest / least viscous at the very end of the nozzle or it'll jam. Also, to get the ship to stay in place while you're printing it you'd need to stick it to the bottle (use a "raft") and that would uglify it considerably.
With a big enough bottle opening, and a flat bottom, yeah I think it could be done though.
