The original NCC-1701, Constitution-class starship. Boldly going where no Thing has gone before.
Captain's Log, July 7, 2013: Version 2 is now available. Look for "NCC-1701_V2.zip". Gaps have been increased to 0.3 mm and seem to work well with a little edge cleanup. I've also added a display stand in the shape of the original series badge.
Just print all 10 components and glue them together. Use a piece of 1.75 mm filament to support the deflector dish. I used a contact clearance of 0.2 mm for the pylons. If this does not work, I'll post a revised model. Happy printing!
UPDATE, 7/7/13: See update in description. I also recommend not gluing the nacells to the pylons, or the pylons to the hull. That way you can take it apart for travel.
