Compact Load Balancer, up to 27 In / 27 Out

This vanilla-friendly setup sends all inputs equally to all outputs, making it perfectly balanced. It scales to any amount of plugged inputs and outputs (up to its size), meaning that the balancer works fine when fewer than all ports are used. Ports are grouped by color in horizontal trios. To draw equally, use a whole trio before going to the next trio. If all ports from a trio are not needed, feed the remaining ports back to inputs. There is no need to feed back any empty trios. Input side is yellow, output side green-white-purple, and all the rest are whatever colors you have in color "FICSIT Factory Swatch" as standard. Please rate and review, so I can improve my designs.
