About this 3D model
Welcome to the Sci-fy! There are two types of corridors. You could join together thanks to a link-door between them. Mechanical doors, elevators and long corridors where you can find closed or open doors. Each corridor has a joint for their hangars and you could put your ships or big miniatures like mechas there. https://www.kickstarter.com/projects/zaxis/modular-stages
