as the name apply this mod is for a one Chest (there may be more chest in the upcoming updates) and this chest have 84 slots with a simple crafting recipe with you only needing 2 diamonds 6 logs and a chest
the crafting recipe is NOT shapeless (shapeless mean you have to make the SAME recipe every time you craft it) i think now i will not make a fabric version sorry but i maybe be able to make it at some point i will update the mod but may take a while because i have to update to all versions 1.15 1.16 1.12.2 so there will be delays but it's so hard as long as idea is simple.
