Nauticam WWL-C collar replacement with loops

The rubber grip collar on my Nauticam WWL-C wet lens/port fell off after a dive. The rubber was very soft, and probably got cut on a rock while shooting a photo. I made a replacement collar with TPU, which also has the benefit of being tougher material than the original. I added a pair of loops on either side to allow adding a lanyard that clips to the housing. It is often a good idea to remove the lens underwater just to release trapped air bubbles. A lanyard prevents you from dropping it, resulting in damage or losing it. I used fishing line and a small clip to attach to the housing.
