Space Cube Mod for Minecraft (1.21.7, 1.20.1) introduces a brilliant solution to one of the most common challenges in survival building: limited space. With this mod, players can craft and place a unique block called a “Space Cube”, which contains an entirely separate interior dimension. By using a special device, you can enter the cube and build or store anything inside it essentially allowing one block to contain an entire mini-world.
This concept works much like a pocket dimension. Whether you’re a redstone engineer, builder, or storage hoarder, Space Cubes let you organize, expand, and isolate your creations in ways not possible in vanilla Minecraft. It’s especially useful for compact bases, secret rooms, technical builds, or server-safe player storage.

Features:
- Add “Space Cubes” to the World:
- Each cube acts as a dimensional container with its own interior space
- Enter the Cube with a Special Device:
- Right-click the cube using a provided item to teleport inside
- Infinite Design Possibilities:
- Build storage rooms, hidden lairs, farms, or redstone contraptions inside one block
- Efficient Use of Space:
- Perfect for small bases, storage systems, or aesthetic compact builds
- Survival-Friendly: Fully craftable and balanced for survival gameplay
- JEI Support Recommended: The Just Enough Items mod is suggested to view crafting recipes
- Fabric-Compatible: Built specifically for the Fabric modloader
