This model was designed using a butt joining method in which each fuselage section is built with a front and a back frame and those are then butt joined ( glued ) to the section in back of them.
While it sounds like a simple task, often it is not a clean transition ( after all you are working in paper and not machined metal precision cut parts ).
So I decided to add glue tabs to each part ( except the extreme nose cone and the last aft section ).
This is a more common method and often leads to better results ( but the choice is yours ).
Here are the parts:
and a close up of some
