Space-saving storage is a mod that allows us to create chests and backpacks with variable storage capacity, that is, we can create our own backpacks or chests of greater or lesser size from storage, according to the amount of materials we have for their manufacture and according to our storage backup of objects.

These new backpacks or chests (chests will look the same as normal chests) should not be crafted in the crafting table, but in a new item called “Builder”. This object will tell us what materials and how many we need to make a chest or backpack of “X” size or capacity. Capacity is determined by rows and columns.
