About this 3D model

This will be a real nice display at a desk. Now the rectangular hole on the aircraft is 6 mm by 3.5mm and the display stand's joint is 5.5 mm by 3.5 mm. I print out the two parts with my M3D printer and they are able to joint together without any superglue. But If you are using a better 3D printer then I am then most likely you can see the 0.5 mm gap. If that is the case I suggest you to use some superglue to joint them, however, you should able to fit them in without any superglue. Anyway give me some feedback if you could.
