I don't do that scale but I like that as some sort of 28mm engine or warp drive, maybe with the vanes replaced by piping...
It's got a scale? News to me.

The kit in general is a parts gold mine for all sorts of things, though. If you're looking to bulk out your bits box with all sorts of odd machine parts, antenna, gun turrets, and fuel tanks it's a good buy even if you never actually need a space station as such.
