This is a complete set of files for the 8-window Seaview submarine from the movie: Voyage to the Bottom of the Sea. 
 
This version includes the two-story control bridge as well as a custom-engineered solution for thrust reversing if you choose to make this model functional as an RC submarine. 

Assembled Length: 2380mm (94 inches)
Assembled Width (at manta fins): 475mm (19 inches)
 
Hull thickness is modeled at 3mm, so bear that in mind if you choose to scale the files down for a smaller model. It is not recommended to go less than 2mm wall thickness, which would net a model length of approximately 1.66m (65")
