Moonbase 1 standard

Moonbase is a modular LEGO space-themed community building standard. The goal of moonbase was to create an easy to follow standard that would allow builders from around the world to build separate "modules" that could be connected seamlessly in a large layout. A layout can consist of 1 or 2 modules or contain hundreds. Each module is connected to another by an airlock corridor. A few other simple rules should be followed but after that anything is possible. A moonbase module can be anything a builder can imagine, in any shape or size. Additional features like monorail, moonway and giant shipyards can be added to further unify a layout.
