A time back when I was running a 'regularly' scheduled Traveller game, I had some high quality copies of various deck plans printed then such were 'trimmed' down following the ship's outline.
One side was left a solid color to represent the ship either dock in orbit or having landed dirtside, the other had a 'generic' deck plan of the ship's interior.
One suggestion, I did upscale a few copied deck plans to 54mm, that allowed for use of the atypical plastic army man to be incorporated into play. With the sheer number of different 54mm figures by the Marx Toy Company alone, I had my choice of astronauts, soldiers, civilians and select monsters and dinosaurs to be crew and aliens alike.
Truly cool was the 54mm set-up allowing the ship's mascot to be properly represented and present, such being a rather large bulldog named Churchill.
