The basic design of this helps designing relays faster and possibly more efficient.
It would allow the copy and pasting of different relays based on where you would want it to go.
The design is pretty simple and make it easier to place links where they are needed.Here is a image basically explains what i'm talking about.

Basic explanation :
The F print fires the way the print is facing
The L print fires where the ends face in 2 directions.
The T print fires where the ends face in 3 directions.
The U print fires up
The D print fires down.
The C print is a manual event brick.
When applied you may have a raw skeleton like this.You can apply it into the walls to make the relays seamless into the build
