ShulkerLayers
A Fabric mod for Minecraft that lets you pack shulker boxes inside shulker boxes, with a configurable nesting depth.
What it does
Vanilla Minecraft blocks placing a shulker box into another shulker box. ShulkerLayers lifts that restriction in a controlled way: every shulker box gets a hidden layer value, and a higher-layer box can hold lower-layer boxes inside it. This lets you build compact, organized storage without spiraling into infinite recursion.
How it works
- Layers. Every shulker box has an integer
layer(0 by default). A regular crafted/looted shulker box is layer 0. - Upgrade recipe. Surround any shulker box with shulker shells in a
+pattern (same as the original shulker box recipe) to bump its layer up by 1. The output keeps the input box's color, contents, and custom name. - Nesting rule. A box may be placed inside another shulker box only if the inner box's layer is lower than the outer box's layer. So a layer-0 box fits into a layer-1 box; a layer-1 box fits into a layer-2 box; and so on. Boxes of equal or higher layer are rejected. This guarantees you can never nest infinitely.
- Tooltip. A box with layer ≥ 1 shows its layer in its tooltip.
The upgrade recipe (where S = shulker shell, B = any shulker box):

Configuration
A config file is created at <game>/config/shulkerlayers.json on first launch:
{
"maxDepth": 3
}
| Key | Type | Default | Range | Description |
|---|---|---|---|---|
maxDepth |
int | 3 |
0 – 64 | Highest layer a shulker box can be upgraded to. 0 effectively disables the recipe. |
Mod Menu Support
With Mod Menu installed, maxDepth can also be edited in-game from the mod list — changes apply immediately (singleplayer), no restart needed. Mod Menu is optional: without it the JSON file is used.
