How to make an infill for gcode

I’m trying to make an infill for a fairly small part with grasshopper, but it doesn’t work.
I’m trying to create a zigzag pattern using endpoints, such as curve frames, for a shape between the outer and inner shapes, but it didn’t work.

Not sure this is what you want, anyway… (26.2 KB)

Thank you for answering!
This is almost what I want to make.
