A blueprint is a special set of instructions that allows you to convert items from your inventory into modules or other items.
To use a blueprint, go to your Private View and select “Inventory”. Then, find the name of the item or module you want to make. If you have the necessary items, you can press the “Make It!” button to create it! You only need one blueprint to make as many items as you'd like providing you have all of the required items in your inventory.
