RS3: Research ship

A model of a universal research ship for FDM and other technologies. The ship can float, but if it is made of PLA filament and you fill it with water, it will sink. The draft is quite steady, you can compensate it by placing a load into the rear cargo area. The model has several individual parts which could be put together with the rest of the model or removed, so you can see inside the model. The ship contains an indoor harbor for submarine - it's not any error in stl file. The model has no real pattern, it is my own design.
