EDIT 04/23/2018 Added a version that accepts a standard X-Wing Miniatures stand.
I always like the design of the Corellian Star Shuttle, but disliked its canon length (80 meters). I've resized it down to a more manageable 18 meters, added egress hatches and remodeled the cockpit windows to reflect the changed length. Added a shallow bottom to flat underside.
Additionally, the resized version scales well with interior deckplans for the Traveller RPG's 20 dTon Launch:
Default model length is set to 66 mm, so matches well with X-Wing Miniatures 1:270 scale.
