Full Slabs
by Micalobia
Full Slabs adds vertical slabs and mixed slabs that share a single block space, for players who want more shapes in their builds.
What it does
Vertical slabs stand upright against a wall rather than lying flat, and mixed slabs let two different slab types occupy one block space, with each half breaking on its own, in the manner of the KleeSlabs mod. Crafting uses new recipes that add steps beyond the ordinary slab recipe, so the set is not limited to placing shapes that already exist.
Placement is controlled by a mode that cycles through three options, changing how the two halves of a block are positioned. A lightweight overlay previews which half will be placed or broken before the action is taken. The mod is built on a single codebase for both loaders through Architectury, and it supports Blockus and Mo Glass blocks as extra compatibility.
Installation requires Architectury API, Fabric API and MidnightLib. The client and server both need the mod, and files are published for Fabric and NeoForge under the MIT License. The source code is available, so the license terms apply to any use of it. Builds cover 1.16.5 – 1.21.10, with the latest file, 4.0.3, dated 2025-12-01.

What the author says
Vertical slabs and mixed slabs for modern Minecraft. If you’ve used “vertical slab only” mods before, Full Slabs maintains that simplicity and adds mixing and interaction affordances on top, without recipe clutter.
