Star Trek Crossover Protector Class fan design

Galaxy Quest Protector bits from https://3dwarehouse.sketchup.com/model/u32d80e90-bb8b-48a1-a1aa-7cb75db55bf4/Sci-Fi-Series-NSEA-Protector-from-Galaxy-Quest-Full-Model

I've seen some fan designs here and there and had to throw in. I think the one I saw was Ambassador Class one, but it didn't feel like the parts meshed. So, special drive experiment on a Constitution Class hull, deep space, long range exploration.
