Factorio Blueprints

Modular Hub/Mall blueprint with three prefabs (Assembly Machines, Inserters, and Belts)

Red lights means input failure. Yellow lights means working. Blue lights means product completed.

• Constant Combinators along the left edge request items into the warehouse below it. Whether these items are belted in or produced further up the chain is automated.
• The constant combinators for belted-in items should be set to the expected resource type.
• The Constant Combinators along the right edge are for the inserter indication color.
• If you want the completed products to aggregate at the bottom, you can put your desired product state in the last constant combinator on the left.
