This is the Atlas Class from Star Trek Online as requested from trekkie1481 in the comments on the Ranger Class that I did. The design of the ship was both love and hate for me, so I added and tweaked it a bit. I slightly raised the pylons so the Bussard Collectors on the twin nacelles weren't obstructed by the saucer. There also weren't any "grills" on the interior of the nacelles like all nacelles in Star Trek seem to have, so I added those. Also, I added a splitter in the conduit that runs from the header of the grills to the mid section, as opposed to the conduit just running between the nacelles.
There are also two versions of the nacelles. There's the "to scale" version, which is the normal version. There's also the "big" version, which are 25% larger. I like the larger version personally because it makes the dreadnought look more powerful when sitting next to the other ships. The preview pictures show the "to scale" version.
I don't actually have this ship in game, so I had to use the original artist's concept art and whatever screenshots of it I could find.
I scaled this down to 75% to fit my print bed. It is to scale with all my other designs with the exception of the Archer class.
You might notice the nacelles have some printer issues. I had to clean out the hot end after printing this, which is the first time I've done this. There were some partial blockages in the hot end that make the nacelle print wispy.
