1. Locate your script brush folder. This is what the path is for me: C:\Users\your_name\AppData\Roaming\.minecraftAxiom\config\axiom\tool_presets\script_brush
2. Copy the nbt files of your choice into this folder

Alternatively, you can copy the lua source code directly into the script brush in game (this seems easier to me)

1. Open Editor Mode in Axiom
2. Select the "Script Brush" in the tools tab
3. Look through the script presets and select your desired brush
4. Use it like a normal axiom tool!
