Didn't get a chance to slice this. This will be a very difficult print for anyone. The nacelles are just so exaggerated in length for that sleek appearance. The saucer section is difficult to print due to its floating segments connected at only 4 points, and then the floating sphere in the middle.
I attempted to print this one at small scale flat with support all along the bottom but wasn't happy with the rough belly. I also tried a little larger scale with the nacelles vertically printed but they ended up falling over on me since they're about the dimensions of a pencil.
I'll give this a shot again one day, but I just want to share it with you all as well.
Again, not perfectly accurate or anything on this one, this was just taking a stab at it with some early reference images.
Good luck!
