Left wing additional hole for cables in ribs 1, 2 and 3

The 12mm grommet is a bit small for all the cables. I did not want to enlarge this hole any further, and the next larger size of Wurth grommet was 20mm and I did not have any. 20mm is unnecessarily large for the wire bundle, anyway. In the right wing there are additional holes as there is no pitot-static, so I will just use one of these. In the left wing the pitot and static lines occupy the remaining existing holes, so an additional hole is called for. So on advice from Sling as to location I made an additional 9.5mm hole in each of ribs 1, 2 and 3.
