Between Structures¶
This approach requires a Freighter. The most efficient option, would just to fill the Freighter with all you need to move between structures. If you use a similar setup described in Hangar, then keeping everything sorted is an important factor.
In order to move everything while keeping it sorted, I have 4 Enormous Freight Containers in a Freighter. Every Container is named similar to the project it belongs to. In the target structure another container with the same name is waiting.
Depending on the amount of materials you need to move, using smaller containers might be more useful.
