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.
3D modeler Mindless-Productions created this version of an Akira-class transporter room. Since it’s not a canon build, it can easily substitute for other non-canon transporter rooms.
