This is 3D printable model of the Neo Constitution Class NCC-1701-G Enterprise from the Star Trek. It is a kit. The different colored parts are separated for easier printing.
If you prefer this ship with its original name and registry of the USS Titan-A, there are alternate kazettes and stand so you can indeed have that.
Pieces of the necelles and some details need to be separated into separate models in the slicer ;)
In the suffix of the files, there are color codes:
bl-blue
w-white
d-dark
b-black
r-red
Files without the sufix are done with grey color
For the assembly, please have a look at the following video.
