This seems to work well for vanilla survival. A couple suggestions:
1. Find space for grow pots near the fridges. I think that extra layer the ceiling can be cut and the blocks put into the floor. Might need to reinforce afterwardd.
2. Maintenance corridor by the warp drive to the back of the engines.. I guess not really needed with a repair station but I like to be able to get everywhere in the ship without god-mode. Can be a narrow partial block passage located where the console is opposite the pentaxid tank. Maybe with a radiation warning sign.

Sorry RE version is 1.10 I can't type :(

Built her in my Reforged Eden 10.1 game but the generators explode when powered up. The ship can't support itself without a massive power and CPU upgrade in RE
