This mall, is neither fast nor optimal.
You can select any early game items, in any assembler and it'll produce it. Everything will be saved in a single storage box.

It is designed to be very early game, and produce any items I need while I deal with 6 landed dark fog relays attacking me in hard mode.

The first 3 assemblers are set to
 - Gauss Turret
 - MK1 Belts
 - MK1 Sorters

You can set the next 3 to any of: (just set the recipe don't need to change anything)
 - Tesla Tower
 - Wind Turbine
 - Assembler MK1
 - Splitter
 - Mining machine

If you connect the stone lane, you can also produce:
 - Depot MK1 (stone connected)
 - Smelter MK1 (stone connected)
 - Thermal Power plant

You can change the items you need during game play actively.

You can even hook up a matrix lab at the end and produce "some trickle amount of blue science" with the leftover materials.

The sushi belt is configured to carry, per minute (when saturated)
 - 90 iron ingot
 - 90 magnetic coil
 - 45 circuit board
 - 45 gears
 - 45 stone bricks

this leaves only 45 empty spaces per minute and I left it at that because it's dangerous to try to fully fill sushi belts with just sorters.

The blueprint is split into two parts to fit into "mass construction 1" without further upgrades.
