1. Place an Interface with a Autocrafting Upgrade.

  2. Configure the resource in the Interface to keep in stock — autocrafting will trigger when needed.

  3. To make the stocked resource accessible to the storage network, attach an External Storage to the Interface.

  4. Set the External Storage to "extract-only" mode. This prevents the network from inserting resources into the Interface, ensuring it only extracts from the stocked supply.
