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.
RedShoulders created the Aries class shuttlecraft, which isn’t canon, but perhaps it fits into your game.
looks like a slightly larger Type 11

but with runabout style interior.
This is a great design
