After getting the item, you will be able to make it at the Replica Station in the Curator's Office. You only need to have had it in your inventory for the recipe to be unlocked. After making it for the first time, the recipe will disappear from the Replica Station, but you will be able to make more at the blacksmith's forge in the Crafting Room in The Safehouse.
