Don't know why, but that plane on the left looks like it crashed on the deck of the boat and is nearly half the size. 

I'm not sure what size of nozzle was used as this is not a 3D print I made myself. I think it would be safe to assume that this is a 0.4mm nozzle though. For reference the 3D Printed Akagi here is a little over 5.5" long.
