A Planet wide mall... that creates all items... slowly,... useless. But enjoy!
Load some drones and vessels into the ILS at both poles and wait approximately 43,764 years for the mall to completely fill. Or.... import as much as you want of all different pieces to speed up the process.
On the actual bus the buildings/final products are set to supply but everything else should be set to demand, so importing from the poles should help fill up the bus.
Be warned, it's super inefficient.
