For Sector 2 I also used the pattern available here. The problem with that sector but also the next Sector 3 is that the lower radiators are levelled with the SM skin. In other words if you want to be accurate you can't used printed radiators and just glue them onto the SM skin, you need to cut the original model so the lower radiators will be fixed into that hole. The first thing was then to fix the pattern to allow cutting the hole within the SM model.
