HerrShulker is a fork of the popular MrShulker mod, bringing compatibility to MC1.21.10+. The mod allows players to craft Shulker Boxes with another Item on an Anvil so that the Item will display on the Shulker Box as a label when placed in the world.
📖About HerrShulker
HerrShulker is a compatibility fork of the MrShulker mod for Minecraft 1.21.10 (and probably some others) that lets you personalize Shulker Boxes by attaching any Item to the lid. Combine a Shulker Box with an Item in an Anvil, and the Item will display on the lid — both when placed in the world and in your inventory. Because as everyone knows, Chest Monsters are legitimate storage systems!
In addition to the Shulker displays, the mod lets you sneak + right-click while holding dye to dye shulker boxes in the world. There are also commands that let you customize the scale of the item displays.
The mod is required server-side, but optional client-side. Dye functionality works without a client install, but clients without the mod will be unable to see Items displayed on the lids of Shulker Boxes.
