You need a wire bended in a diameter of around 80mm, cutted to the needed length.
Further you need a thread to pull the spider out of the box. The thread has to be fixed at the lug on the spool. Fix the other end to the lid at the correct position. Slide the lid a couple of time and find the right length.
