There are some great fan-designed 3D models, many very faithful to the original blueprints, that a snapshot could work quite well for a tabletop battle-grid. Credit always goes to the 3D modeler. I only add missing bits and a bit of colour. Search here for the full series.
Here is a Type-6 Shuttle cutaway designed by Marcel V.. I have a larger single-ship version for 8.5″x11″, and one where two smaller ships are on a single page. I removed the ship name and registry number from the front to enable general use.
