Nice work! Your blueprints are some of the most aesthetically pleasing, yet still very functional and compact ones I have seen so far! Deserves way more views and recognition in the Satisfactory community!
There is no need to link them on every level. On the lowest level (sandwich level) there is splitter and merger sitting on the end of vertical manifold. One can just hijack that output and daisy chain all stacks into mergers, technically funneling all plates into 1 output.
