Item Duplication
by Spartacus_01
Item Duplication, a Forge economy mod for Minecraft 1.20.1, lets players copy items at a crafting table by placing an item in a duplicate crafting grid.
What it does
Players place an item in the duplicate crafting grid and receive double the amount immediately. The process runs at a crafting table, so no separate block or machine is needed. The mod targets players who want to ease grinding, speed up builds that need many materials, or manage resources with fewer limits.
Only the server needs the mod, so players join without installing anything. It is published for Forge only, with a single game version: 1.20.1. The latest file is 1.0.1 for 1.20.1, dated 2025-08-21. The mod is released under the MIT License and is not open source.
Key features
Crafting table duplication
Items placed in the duplicate crafting grid return double the amount in a single step at a crafting table.
Instant results
The doubled stack appears immediately after the item is placed, without waiting or extra steps.
Resource management
Duplication gives access to larger stocks of an item, which can help with long builds and repeated crafting.
Adventure and survival use
Players can use the duplication to shorten grinding in survival or to collect materials for large projects.
