Help creating a solid folded panel

Hey hey folks, I’m doing some studying and I wonder if there was a way to optimize my current workflow to make things less convoluted in the script, here’s what I’m looking to accomplish in terms of 3d solid:

A double folded panel with 1,5mm thickness. as you can see it folds two times to the inside, the second time making a chamfer on the diagonal.

And here’s my current workflow:

Took the surface, took its edges and offset and moved them to create so in the end I could loft all of them into the solid. Just think it’s a method that takes way too much detours and as a beginner I was wondering if anyone could help me optmize it. I looked for kangaroo plugin and saw some folks using it to create origami structures, but I’m quite new to the plugin and don’t know how it works properly

3. Attach minimal versions of all the relevant files

Oh sorry, forgot to attach the gh file, here it is:
