Storage Builds
Storage rooms, sorting systems, item filters, and warehouse designs.
A hopper-based item sorting system that automatically routes items into designated chests. Each filter module sorts one item type using a comparator-based overflow-proof design.
A vertical item transport system using a chain of droppers to move items upward. Essential for connecting underground farms to surface-level storage systems.
A well-organized storage hall with labeled double chests along both walls, item frames for identification, and enough space for 54 double chests (2,916 stacks).
A 16-furnace super smelter that processes items 16x faster than a single furnace. Input items and fuel via hoppers, and collect smelted output automatically.
Which container to use
- Chest
- 27 slots, or 54 when two chests form a large chest. A chest will not open with a conductive block on top of it, so keep the space above free or use something like glass.
- Barrel
- Also 27 slots, and nothing stops it from opening, so barrels can be stacked into walls and floors where chests would stay shut.
- Shulker box
- 27 slots that stay inside when you break the box, so a full box moves as a single item.
- Ender chest
- Every ender chest in the world, in every dimension, opens the same inventory, and each player has their own.
Large chests add up fast: the storage hall fits 54 of them, and at 54 slots each that is 2,916 stacks.
Moving items without you
A hopper passes an item on and then waits 8 game ticks, so one hopper moves 2.5 items per second. A longer chain is no faster, which is why the super smelter spreads its input over 16 furnaces instead.
Blast furnaces smelt ores and smokers cook food twice as fast as a furnace, but they also burn fuel twice as fast, so you get the same number of items per piece of fuel. A dried kelp block smelts 20 items, and kelp can be farmed.
The item sorter sends each item type to its own chest, and the item elevator lifts items with a column of droppers, handy when a farm sits below your storage.
Reading how full a container is
A comparator behind a container gives a signal based on how full it is, counted in stacks: one item in a chest already gives signal 1, and signal 15 needs all 27 slots full. Items that stack to 16 fill their slot at 16, and a tool or anything else that doesn't stack fills it on its own. A hopper reaches 15 with just 5 full slots, so it reacts to far fewer items than a chest does.
Copper chests and the copper golem
Place a carved pumpkin last on top of a block of copper and you get a copper golem, while the copper block turns into a copper chest. The golem takes up to 16 of the first item it finds in a copper chest and carries it to a nearby chest or trapped chest that is empty or already holds that item. It spends 3 seconds checking each chest, remembers the last 9 it tried, and after 10 chests without room it wanders for 7 seconds before it starts over.
That makes golem sorting slow, but it needs no redstone: give each item type its own chest and the golems fill them. Wax a golem with honeycomb, because an unwaxed one oxidizes over time and ends up as a statue that drops what it was carrying. An axe scrapes a statue back, and once it is unwaxed bare copper again the axe wakes it up.
