At 15 studs long, the micro-scale model still shows quite a few features of a real submarine.
About this creation
This is a micro-scale submarine. An view from the back is also available.
It is 15 studs long, but you don't see the studs due to a special design technique. The following image uses colored plates to visualize the interior. Two lamp holders reverse the direction of the studs in the center of the model.
