Loved the original idea and copied it, but made a couple of adjustments:- Altered the friction plate so the 'wings' sit proud and are easier to turn than the flush version on the original. Also modified the wedges and plug elements to contain tabs/grooves which lock the wedges in place and prevent them falling out in the event of the o-ring band snapping, which was the only thing holding them in place on the original.
