CLEAVE

Split by color. Keyed to fit.

Cleave is a local-first 3D model splitting and fitting tool. Use existing color data when available, or paint regions directly on a model when it is not. Then split the model, create the connection you need, and export the pieces for whatever you're building.

KEYED PARTS
The process

Three steps. No guesswork.

01

Import & analyze

Bring in a supported model. Cleave can read existing regions and materials, or let you paint regions yourself when color data is missing.

02

Split & key

Choose where pieces separate and how they reconnect. Use a peg, puzzle key, magnet pocket, or another fitting method.

03

Export & use

Export the resulting parts for printing, game development, fabrication, prototyping, or whatever your project needs.

Joint catalog

Three ways to key a seam.

●

PEG & SOCKET

Friction-fit connection with configurable clearance. Simple, strong, and easy to understand.

⊞

PUZZLE KEY

Interlocking geometry built into the seam for self-aligning parts and optional adhesive.

⊙

MAGNET POCKET

Recessed pockets for magnets with built-in clearance, designed for removable assemblies.

Local by design

Your models stay on your machine.

Cleave is designed as a desktop application. The core workflow can run locally on your computer, so your model does not need to be uploaded to a cloud service just to be split.

Offline workflow — no internet required for normal use.
No cloud processing — geometry work happens locally.
Updates when you want them — connect when a new version is available.
“Cleave isn't about what you use the model for.
It's about making the model fit the way you need it to.”
New capability · Paint & split

No color data? Paint it yourself.

Cleave is being updated so a model does not need existing color or material data. Paint regions directly on the model inside Cleave, then use those painted regions to define where the model should split.

Paint directly on the model — mark the areas you want Cleave to recognize.
Painted regions become split boundaries — use your selections to create meaningful seams.
Keep the fitting workflow — add peg & socket, puzzle keys, magnet pockets, and more.
“Your model doesn't need color data anymore.
Paint the regions yourself, then let Cleave do the splitting and fitting.”
Built for more than one workflow

One tool. Many uses.

🎮 Game Development

Create modular pieces, break apart assets, and prepare components that need to connect.

🖨️ 3D Printing

Separate multicolor or oversized models into pieces and add physical alignment or locking features.

🛠️ Making & Prototyping

Prepare physical builds, prototypes, props, models, and assemblies with controlled connections.

Cleave · Crazy Eyes Studio

Split smarter. Fit better.

Cleave is currently in development. When it is ready, it will be available free on Crazy Eyes Studio.

Cleave will be free to download from Crazy Eyes Studio when it is ready.
