Back Chest

 A chest you wear on your back. 27 slots, up to 72 with 5 upgrades, plus a portable crafting table and furnace.

 

Description: In deserts and other places where leather is hard to find, you still have to carry a lot of stuff. Back Chest is a backpack-style chest made from string and a chest, so you do not need leather. It has 27 slots like a normal chest, and every upgrade adds 9 more slots, up to 72. The latch on the chest changes color to show its level.

 

Features:

 

Craft it with 6 string and 1 chest (no leather needed)

Worn on your back like a thin chest, in the chest armor slot (like an Elytra)

Instant chest menu with an X button, plus a full chest screen (Back Chest on top, your inventory below)

Starts with 27 slots, every upgrade adds 9 more, up to 72 slots

5 upgrade levels: Copper (36), Iron (45), Gold (54), Diamond (63), Netherite (72)

Latch color changes with the level: white, orange, gray, yellow, cyan, dark

Upgrading keeps all your items

Only you can open your own Back Chest

Open it while wearing it, no need to hold it (double-tap sneak)

Deposit everything from your inventory with one tap

Portable crafting table and portable furnace (smelts raw ores, sand and cobblestone from your inventory)

Crafting:

 

Back Chest: S_S / SCS / S_S (S = string, C = chest, middle top and bottom slots stay empty)

Upgrade: MMM / MBM / MMM with B = the Back Chest of the level below, M = copper ingot, iron ingot, gold ingot, diamond or netherite ingot (in that order)

How to use:

 

Craft a Back Chest (see Crafting above).

Wear it: put the Back Chest in your chest armor slot to see it on your back.

Open it without holding it: double-tap sneak while standing still and looking forward. The Back Chest menu opens instantly. Tap an item to take it out. Tap Deposit items to store things. Press the X to close.

Want the full chest screen with your inventory below? Tap Open full chest screen in the menu, then tap the chest that appears in front of you.

Crafting table: double-tap sneak while looking up. A crafting table appears for 45 seconds.

Furnace: put raw ore and coal or charcoal in your inventory, then double-tap sneak while looking straight down. Ores turn into ingots right away.

Holding the Back Chest in your hand also works: tap = full chest screen, sneak + tap = crafting table, look down + tap = furnace.

Backup: type !chest, !craft or !smelt in chat.

Upgrade: craft the next level with the old Back Chest in the middle. Your stored items move to the bigger chest.
