Unrolling surfaces for laser cut

Hello,

I wish to assemble model shown in the above image. I have used panelling tools plug-in. I am able to sort out the pieces since all the modules going to be laser cut, I need smart modules which will save time, material and cost. I have came up with 2 different modules, one which I ideally desire is difficult for me to make it.

Herewith I am attaching Rhino file, any logic from you is appreciated.

Thank You in advance
