Docking Rings
This is an idea for a standard docking system for LEGO® spacecraft. It is done by forming a docking ring with Technic® pegs spaced in a square configuration. The spacing of these pegs is designed so that whether mounted on the side of a wall of a ship (bricks), or in the floor or ceiling (plates), they can still be used to dock with another craft in any of 4 orientations.
