NanoBuild
by BaXu
NanoBuild lets players place Minecraft blocks at half or quarter scale, producing miniature slabs, stairs, fences and other detail pieces.
What it does
Players choose between normal placement, half size and quarter size with the V key, and a size indicator on the HUD shows the current setting. Supported blocks, including fences, gates, torches and lanterns, can be placed as miniatures to build detailed decorations from small full blocks, slabs and stairs. Right click places a mini block, left click removes the mini part under the crosshair, and middle mouse button picks a block and copies its selected size.
The mod adds its key bindings to Options, Controls, Key Binds under Mini Blocks. The selected size stays active after the held block changes and after the game restarts. Functional blocks that are not supported keep their normal vanilla behaviour and are not converted into mini blocks.
NanoBuild is published for Fabric only, for 26.1.2, under All rights reserved, so it is not open source. The environment is client and server, which means both the server and each player must run the mod, and Fabric API has to be present on both sides in multiplayer.
Key features
Half and quarter scale
Blocks can be shrunk to half or quarter size, covering slabs, stairs and fences as well.
Interactive miniature blocks
Fence gates, torches and lanterns work as miniatures, so detailed decorations stay usable.
Size cycling and HUD
The V key cycles through normal, half and quarter placement while the H key shows or hides the size indicator.
Mouse placement controls
Right click places, left click removes the targeted mini part and middle click copies the selected size.

Use cases
Who it’s for: Builders and decorators who want finer detail than full-size blocks allow. Server owners running multiplayer need to install the mod and Fabric API on the server and on every player's client.

GeometryHUD is a Fabric client-side only mod for the same versions, also under the MIT License and open source. Woodcutter is a Fabric client and server mod for 26.1 – 26.2 under the MIT License, and it is not open source. NanoBuild differs by covering 26.1.2 only and offering scaled placement instead of extra stairs or HUD tools.
