A compact(ish) little design that uses vulcanus's foundries and fulgoras electromagnetic plants. technically it makes 89.77 green circuits per second but who cares.
Feed in molten iron down the very middle or on the very edges Feed in molten copper down the "lanes" of the two sections or at the bottom. Has 4 storage tanks built as a buffer. They're probably not needed but i buffer things out of instinct after getting ptsd from complicated mods
The module setup isn't made for pure production, I just filled in the space i had with beacons and reached for 90/s. The outer beacons are using green modules to save on the prints monstrous electricity usage but if you wanna squeeze out more then go ahead and swap em to blue or red. Just be aware that producing more means blue belts can't carry it all at once so your have to swap to the new belts or go bot based. (or use those new fancy schmancy inserters)
oh also you can obviously upgrade the modules to tier 3 and make all this stuff legendary but if your doing your probably making your own design and not reading this
