Duplicating Table
by Sumbaii999
Duplicating Table is a NeoForge block that copies an item placed in its first slot, so one press of the Duplicate button returns two identical items.
What it does
Placing an item in the first slot of the table and pressing the Duplicate button leaves two copies of that item in the output slot. The mod covers ordinary items as well as modded items and blocks, and enchanted items keep their enchantments through the copy, which makes it a shortcut for players who would otherwise spend long stretches farming or mining diamonds and other resources.
The table is crafted from one Crafting Table, four Iron Ingots and four Redstone Dust, and it has to be mined with a pickaxe to be collected again. It runs on both client and server, so the server and every player need the mod. Files are published for NeoForge only, for Minecraft 1.21.4, and the latest file is 1.0.0 from 2025-04-24. The mod is released under All rights reserved, so it is not open source.
Key features
Single-press duplication
An item placed in the first slot is copied to the output slot when the Duplicate button is pressed.
Diamond copies
Stacks of diamonds can be duplicated the same way, giving players a fast alternative to mining.
Enchantments preserved
Enchanted items keep their enchantments after duplication, so the copies match the original.
Modded items and blocks
Duplication is not limited to vanilla content and also works on items and blocks added by other mods.

Use cases
Gathering resources quickly
A player who needs a large amount of a resource can duplicate what they already have instead of farming or mining for hours.
Copying rare gear
Enchanted tools and armor can be copied so a player keeps a spare set without repeating the enchanting work.
Who it’s for: Players who want a shortcut for collecting resources, and server owners who accept item duplication as part of their game rules.
How it compares
Infinicrafts runs on the server alone, so clients need nothing, and covers 1.21.4 – 1.21.10 under the Creative Commons Attribution Share Alike 4.0 license. Renewable Gravel and Sand also runs on the server alone and is built for 1.21.7 under All rights reserved. Duplicating Table is for 1.21.4 and needs both sides, so it differs from both in environment and version.
