Canisters are containers that hold various items.
Medium Fluid & Soil Canisters are crafted in the Small Printer and allows for greater storage of Soil and Hydrazine, up to 24 times the amount that a Small Canister can hold. Small Canisters can both deposit and withdraw soil from the Medium Fluid & Soil Canister, allowing for some automation of filling a Soil Centrifuge. These also pair well with Pavers and Drills to quickly gather soil and pave pathways.
Medium Resource Canisters are crafted in the Small Printer and allows players to store one kind of Resource at a time, holding 32 nuggets (8 more nuggets than a Medium Storage Silo). They are useful when used with other Automation items.
Medium Gas Canisters are crafted in the Small Printer and allows players to store more of one gas than other storage items allow, can hold up to 32 full canisters or 160 units of a single Atmospheric Resource. They cannot hold other types of resources, including Hydrazine, as it is a liquid.
Large Resource Canisters are crafted in the Medium Printer and allows players to store the maximum amount of resources possible, at 400. This is 16 greater than a Large Storage Silo B holding 12 Medium Resource Canisters. When paired with other Automation items, they can allow players to craft a great amount of items without needing to interact with modules.
