Kündekari voronoi pattern

Ref: http://www.grasshopper3d.com/photo/k-ndekari?commentId=2985220%3ACo...

Hi,

I want to use this amazing voronoi Kündekari pattern for segmentation of a shell structure. 

With two modifications:

1. Each interlocking part shares its edges with neighboring parts. I want to separate the edges by creating another surface of user-defined width in between the edges.

2. Join ends of the hexagon from which this pattern has been derived using a triangle(red triangle in figure below). Actually, can also be done manually if its too difficult to script in GH.

Also, I want to control the groove height and width.

Could anyone share the script or help me create one for this purpose?

Best regards,

Sushant
