This model is one of my favourites, it is my own interpretation of the USS Kobayashi Maru from Star Trek online and Star Trek the Wrath of Khan (though you never see it on screen).
I custom designed the cargo pontoons and had them 3d printed for me. The original kit is the USS Reliant, miranda class. The rear cargo is a resin part from Multi Verse Models, the saratoga conversion kit. The cargo deck on the saucer is completely scratch built, but I lost a cargo door in my recent move.
Enjoy!
(Also can someone help me with uploading images directly from folders? I don't like that photobucket isn't free and has that watermark)
