Blender Jigsaw Mesh

Jigsaw mesh in Blender 3D.  I created this for use in "cutting" other meshes into jigsaw puzzle pieces using the Boolean modifier.

When using the Boolean modifier, you should be able to use the Intersect operation.  If that doesn't work, use the Difference operation.

A minor caution: This is not the cleanest of meshes and it is high-poly.  As a result, using it will be processor-intensive.  However, it does serve its purpose.
