Storage Drawers Auto-Sorting Walls

A classic Storage Drawers build:

1. Lay out a wall of Full Drawer 4× blocks in a 6-wide × 4-tall grid (96 slots).
2. Place a Drawer Controller somewhere in or against the wall.
3. Insert a stack of each item you want to sort into its drawer. The first stack locks the slot.
4. Lock every drawer with the Drawer Key so they keep their bindings even when emptied.
5. Run a hopper or other pipe into the controller — every dropped item routes to its locked drawer.

Once built, drop a stack of mixed loot onto the input chest above the hopper and watch the wall sort itself. Add more drawer columns as you collect new item types.
