Survival Constructor (Inventory)
The Survival Constructor is not a placeable device (and therefore has no item image), but can be found using the button at the top right of the player's inventory.
This user interface can be used to craft various early-game items, including the Portable Constructor.
NOTE: Initially the (placeable) device Portable Constructor was named "Survival Constructor". This device was later renamed to Portable Constructor (as it is currently). Following this, the Survival Constructor (User Interface) was added to the inventory screen.
