STL — SHADOW SUB
A submersible aircraft carrier, surfaced. Up to no good in the lane.
Binary STL in millimetres — prints ~200 mm long (1:626). Exported straight from the Hornet Bay sim's model code (hornetbay.com): wheels up, weapons off, ready to slice. The zip includes PRINTING.txt with scale, printed size and slicer settings.
For personal use — print one for your desk, your squadron, your carrier. Don't resell the file itself.
