The Tool Kit Mod (1.21.8, 1.20.1) is a lightweight yet powerful enhancement tool for builders, map makers, and technical players who use structure blocks. Designed to overcome the limitations of vanilla structure block mechanics, this mod significantly increases size boundaries and provides greater control for handling large-scale structures. Whether you’re creating massive adventure maps or exporting large builds, Tool Kit gives you the flexibility to work beyond Minecraft’s built-in restrictions.

Compatible with Fabric, Forge, and NeoForge, the mod is an essential utility for advanced creators.

Features:

Expanded Structure Block Size Limit:
- Increases the maximum structure size from the vanilla limit of 32 blocks to 512 blocks, allowing you to save and load far larger builds.
Larger Bounding Box Limit:
- Extends the structure block’s bounding box from 64 blocks to 128 blocks, making it easier to capture massive creations without needing multiple structure blocks.
Core Utility Focus:
- The mod does not introduce new blocks or GUIs it simply enhances the existing structure block functionality.
- Useful in both creative singleplayer and server-based world editing scenarios.
Compatible with World Edit and Map Tools:
- Can be used alongside tools like WorldEdit, Litematica, or Schematica to streamline your workflow.
