2.0 made this mod unneeded! It even has a similar solution, with combinators and blueprints!
- Name the logistics group you're using to request items. I recommend putting your username in it.
- Make a combinator using the same group.
- Make a blueprint of the combinator
You can then bring this blueprint into other worlds, and it will bring the logistic group with it. You can use it to request items!
TLDR: Learn how 2.0's logistics groups work. Learning this will eventually lead you to an answer!
