This is based on Nilaus design to centralize complex assembling production in a main polar hub
When deploying the Extension Hub, many of the complex items will come from here or from the Manufacturing Hub (mall)
I only use Mk.II assemblers.
This is an 8 suns setup. Can be upgraded by chaining the suns outward
If demand is high, I may do an unpowered version to allow anyone to build the hub as soon as ILS are unlocked
