I’ve been planning to start using MILS plates for my modulars for a while and it turns out there’s a few different schools of thought. In the end, I decided to go with color coded corners (for easy identification at shows and such) rather than solid colored 2x2x1 bricks, along with the usual technic brick connectors on each side of the corners. Another minor deviation from the usual MILS plate that I decided to adopt was adding small arches on each side to allow threading wires for motors and lights and so on. As you can see it’s Superman approved!
