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.
Another agent-p project: a NCC-1701-A impulse engine room. Although designed for the NCC-1701-A, it’s easily adaptable to any era.
