The overhead view might not be enough. Performance issues aside, if I take your sample and rotate the camera to the overhead view, the wires that power the Arduino overlap in a kinda confusing way. It’s even worse if you swap them around, with the wire colors randomly mixing in the middle (but it is also broken when looking at it from the side). A 2D-first design wouldn’t need to worry about it, but it would instead route the wires in a way that avoids overlapping wherever possible (and two parallel wires would be quite trivial).
