Wasp- Retrieve duplicate faces

Hello

I’m using wasp to aggregate some geometries and I need to retrieve the faces of the cubes that are touching each other. Thought I’d go about it by culling the duplicate mid points and extract the culled ones but I can’t seem to get it working. Any thoughts how to do this?

Your help is much appreciated :slight_smile:
