i know a lot of you can turn Balls, but I hate throwing stuff away, so I found a way to recycle car air freshener bottle tops.
We all know these.
Clearly I had to find a way to salvage the tops, the screw hole was just simply to big to tap but a M8 nut was a tad too big for the hole.
So I heated up a M8 nut with my heat gun and simply pushed it into the original screw hole. It melted perfectly in to place and by pushing some excess plastic over the nut it is very secure. One less piece op plastic to end up in a landfull.
