Slab Machines Mod – Compact Slab-Sized Machines
The Slab Machines in Minecraft help save space by turning common machines into smaller slabs. This change reduces the chest size by half but keeps the same storage space. These slabs can be stacked, giving you more than double the storage in the same area compared to regular double chests.
You can also use slab furnaces to smelt items, although the maximum is reduced to 32. But stacking them allows handling more types of items in less space.
This mod introduces slab TNT blocks that cause about half the damage of regular TNT.
Crafting tables can also take up less space when turned into slabs. Additionally, these slabs can be stacked together, significantly reducing the space they occupy in your structures.
