Overview of the bluepacks-relevant part of the factory
Zoomed in at the inserters factory so you can see what's going on. I'm quite proud of the one, even though I suspect it's highly unnecessary. It keeps electronic circuits on the left side of the lane, while the right lane always has Inserters, then Fast Inserters, then Filter Inserters, then Smart Inserters. Why? So I can keep all my inserter factories in a neat row of course!

There is a small bottleneck with the electronic circuits, but nevertheless it keeps humming along, as I took this picture you can see that 4 out of 5 Labs had blue science packs in them.
