This is a rough concept for a Star Trek TOS-era starship. The design is moderately based on that of the NX-class starship, but updated to fit the TOS aesthetic. My CAD skills continue to improve marginally as I use Blender more, but I am pleased with the end result of this project.
Regarding the materials, SketchFab doesn't support Blender materials so I simply remade them in the SketchFab 3D editor.
