These are the two study models that where made for the unproduced Star Trek movie "Planet of the Titans". They are based on the designs by Ken Adam and Ralph McQuarrie. The smaller ship was labeled B-44-CLN and appeared in the surplus depot Z15 in TNG "Unification I", probably this shot was originally created for "The best of both worlds", so it could be that this ship was in the Battle of Wolf 359 too. The larger one was partially visible behind the hub of the spacedock in Star Trek III "The Search for Spock", when the Enterprise enters. I scaled them, that the saucer diametet is the same as on the TOS Enterprise. That makes this 1/7000, but can also be any other scale. I added a socket for the use in Star Trek Attack Wing.
Be aware that the price for Detail Plastic Shapeways calculates for this includes a per file and a per part fee. You only have to pay the per part fee for this when I combine this with one or more items in Detail Plastic. So ask me to combine all the items you want to one single file to get it cheaper.
If you need this in another material, size, quantity or combined with one or more of my other parts for cheaper printing, just let me know. I will try to make it as you need.
