I have been working on a standard module design for building at a nano scale. Inspired by Twinlug’s micro building standards.
The base consists of a 8×8 plate with a 1 stud deep slot in the forth position from the left, and a 1 stud tab in the fifth position from the left on all 4 sides.
This is a modular baseplate that can easily slide into any other baseplate to form larger city blocks, or clusters of blocks.
Of course, you could just as easily build specific modules for corners or edges that don’t have slots and tabs on the outside edges, but the main purpose of this modular system is to allow maximum flexibility for groups of builders to come together with pre-built modules and set up a multi-block city on the spot, without extensive planning.
There are two additional parts that are used to close off a group of baseplates. A corner cap and an edge cap.
Here is an example of the modular system in a 2 base mini block configuration. Bases can be configured to represent a city block, or simply to showcase a particular building on it’s own.
