Chai's Build Tools

by Chai · on Modrinth

A set of tools that are useful for building; a wrench to rotate blocks, a trowel to place random blocks, and a cloud bucket to place blocks in the air

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.21–1.21.1Newest
Minecraft 1.20–1.20.4

⬇ Download for 1.21–1.21.1 ⬇ Download for 1.20–1.20.4

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

About

Chai's Build Tools adds a set of tools that are useful for building in both survival and creative. The recipes were thoughtfully designed to be introduced with each new metal you obtain (copper -> iron -> gold) and give another crafting use for the ingredients.

Wrench

The wrench can rotate all kinds of blocks, including torches and ladders onto neighboring supported walls.

Trowel

The trowel will place random blocks from your hotbar.

Cloud Bucket

The cloud bucket can place unlimited cloud blocks that disperse after 4 seconds. It can also place these cloud blocks in mid-air too.
