For making very fine lines on plastic, I would score the plastic with a blade where you want the lines, write over with a Sharpy, then immediately rub out with finger or eraser while it is still fresh. Some black ink will remain in the scored groove, but the bulk of it will removed and you are left with a very fine line.

Now I'm hacking a slotted ruler for placing Sun/Moon/planets. The scale is 1° per millimeter. What type of marker would you recommend for doing such marks? I'm afraid usual pencils will leave difficult to remove graphite dirt.
