Available Files

The schematics are split across different variants and game versions. For gravity block dupers, choose between the base version and the color swapping variant. For the concrete factory, use the 1.18.2 to 26.1.2 schematic or the 26.2+ schematic depending on your game version.

How to Use

1. Flick the lever to turn on the sand duper.
2. Hit the Note Block on the End side to toggle the concrete factory.

Important Notes

• Do not turn on concrete mode while duping anything other than concrete powder.
• The on/off switch is not spamproof, so do not spam the lever.
• The skeleton heads can be replaced with any head.

Before you build

• Larger end side than slower designs.
• Mode can be switched only while factory is active.
