Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

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.

Extra Copycats

A small addon for the Create mod that brings a few more flexible copycat blocks to your building palette.

The Blocks

Copycat Collapsible This is the highlight of the mod. It’s a copycat block that you can squash and stretch on the fly with a Wrench. If you need a wall that is only 2 pixels thick, or a slab that’s offset to one side, this is the block for you. It's great for custom siding, thin panels, or filling in those awkward gaps that regular blocks just can't handle.

Left-click a face with a Wrench to push it inward.
Shift + Left-click to pull it back out.
Right-click to rotate the shape, and Ctrl + Right-click to mirror it.

Copycat Cabinet Door A 1x1 door that’s only 3 pixels thick. It swings on a hinge and matches whatever block you put into it. Useful for making actual cabinets or hidden wall storage.
