Hi everyone!

Martin from [Layerlab ](https://www.youtube.com/@LayerLabAustralia)here! I've been working on a new tool for makers, it's called **Snappy**, a Blender add-on that automatically adds clearance between parts designed in Blender for 3D printing.

It’s intended for:

* Sliding lids
* Press-fit connectors
* Snap-fit clips
* Plugs and sockets
* Parts that need to fit together reliably

The workflow is simple:

1. Select the base object.
2. Select the fitting part.
3. Choose your clearance.
4. Move the part into position.
5. Create the cut and export the models.

There are two versions:

**Snappy Free** makes it easy to create accurate, clearance-adjusted fitted parts using a simple one-cutter workflow. 

**Snappy Pro** unlocks multiple organised cutters, custom clearance, protected faces, low-resolution previews, per-cutter controls and streamlined project/slicer export.

Snappy Pro is currently in **Early Access**, and I’m looking for people willing to test it on real projects. Please save your Blender project before testing.

I’ve also created 10 Pro trial keys for testers, first-in best-dressed. Each key works on one computer and expires on 22 August. All you need is your email address for the key to be sent to.

I’m particularly interested in feedback about:

* Models or cutters that fail
* Fits that print tighter or looser than expected
* Performance with complicated models
* Installation or update problems
* Confusing parts of the workflow
* Missing features

Screenshots, printed results and sample files would be extremely helpful. Thanks!
