I took Nautilus 3.0 by HMS82 and hollowed out the main body and wheel house so that lights could be placed in all of the windows.
The wheel house did not come out very clean inside so some scraping and drilling may be required. I added two holes to the wheel house so that you can drill up to the "alligator eyes" on top.
I also added a hole at the base to place a switch.
I also added Fimbul_71's alternative propeller to the files.
