Mods Required:

• Minecraft 1.19.2
• Fabric API 0.66.0
• Cloth Config 8.2.88
• Skylor Lib 1.5.1
• Auto Workstations 1.0 (all versions are labeled SNAPSHOT)

Setup Required:

Any Auto Crafting Table works.
Any Tokenable Furnace hopper works, but higher tiers duplicate more items.
Treat x (such as iron ingot) as any mineral that has a compressed form X (such as iron block) that can be reverted.
Place a recipe of:
xxx
xxx
xxx
in the top crafting table, and place a recipe of X in the bottom crafting table.

Placing iron ingots in the top chest will duplicate them.

Didn't take a good screenshot apparently and don't want to change a bunch of mods again
The structure of the duplicator is

C
V
#
V
#
V
C

where C is a chest, V is a tokenable furnace hopper, and # is a auto crafting table
