This smart mall produces what is requested via the constant combinator (CC), it can be left on a planet when visiting another to manufacture odds and ends, or used on a space platform with adaptions (using the hub instead of the requester chest). Prerequisites must be listed with a higher count in the CC, and all prereqs listed.
It is slow, but seems to work. Requester chest can be replaced with steel container with basics in it (copper, girders, iron, ...). Any assembler can be used. howerj
