Grasshopper Radial Waffle

Hey there,
I’m trying to build a radial waffle with Grasshopper but I’m not getting the result I want. The beams that I bake are somehow twisted because they are following the surface. I’d like to have them straight as shown in the pictures. Does anyone have an advice or could help me? I’m looking forward.
