Factory Block
by LeaveSteve
With Factory Block, a duping block copies items when a player holds an item and right-clicks the block, and the copies work with hoppers.
What it does
Factory Block adds one block that duplicates items. A player holds an item, right-clicks the block and receives copies, which makes rare or hard-to-farm items far easier to obtain. The block also works with hoppers, so it can be fed by automated systems in a storage build.
The mod is a Fabric addition for the 1.19.4 game version, and it needs Fabric API. Client and server both need it: the server must run the mod so the duplication works there, and players must install it too. Clientside duping glitches can also be enabled, but only on servers that support them.
Factory Block is open source under the GNU General Public License v2.0 only. Source code is publicly available. The first file was published on 2024-02-18, and the latest Fabric file is 1.0.0 for 1.19.4, released the same day.
Key features
Item duplication block
A single block copies the item a player holds when it is right-clicked on the block.
Hopper compatibility
The block works with hoppers, so duplication can run from item transport lines.
Clientside duping glitches
Server owners can enable an option that lets clients use duping glitches on servers that support it.
Exploration incentive
Items that once took long farming runs become quick to obtain, which encourages players to explore further.

Use cases
Building with fewer supplies
Players can build freely without collecting large stockpiles of materials, since one item can be copied on demand.
Automated storage lines
Hoppers can feed the block so copies move through a storage system without manual input.
Who it’s for: Players who run survival worlds or creative builds on Fabric 1.19.4 and want quicker access to rare items, and server owners who want to decide whether duplication is allowed on their server.

Until someone puts a new item in the factory block, anyone with an empty hand can pull as many stacks of the item out of the block as they want. This mod was…
