It has 72 assemblers and builds every building in the game.
All inputs are stacked and profilerated. And a beautiful spiral elevator in the middle of the mall.
Assemblers are in the lowest tier so you can build it right after unlocking yellow matrix. Pile sorters are needed for stacking, do not remove them. You can change the speed in which item gets delivered into the sushi belt by upgrading/downgrading sorters on the mezzanine.
Edit: Many thanks to Ludus for the Elevator blueprint. Edit 2: Fixed reinforced thruster sushi feeder Edit 3: Changed the item type of some assemblers to make more sense. Edit 4: Forgot to power a pile sorter so I added a Tesla tower. P/S: I just realized I didn't have any room for a logistics bot assembler, so you may need to sacrifice one building for it ;p Edit 5: Forgot to put sorters for 1 assembler.
