This is the first time I found a satisfying polar design for a botmall. Compared to other botmalls, it has the following features:
Makes all buildings in the game, plus logistics drones.
Relatively small footprint. The mall only uses two logistics distributor boxes per assembler.
Can easily be extended. The mall currently imports 25 materials, but it has space to import 32 in case you want to add more. It also has nine unused assemblers and export slots where you can easily add new items.
Convenience circle: the circle in the center of the design makes some products so that they don't need to be imported. This makes it easier to get the mall going. But if you feel that throughput is too low, you can always add an import to one of the PLSs if you like. You can even delete the entire thing and build those products elsewhere, freeing the pole up for something else, like power generation.
All buffers are set to minimal size, this is to help the mall saturate quickly. You will need to increase the buffers for high throughput items like logistics items, drones bots and vessels, solar panels, smelters and assemblers.
