Todays lid I find very good. Some minor tweaking I will do to get her even better.

I am very pleased with the results of the latest idea. It is very simple to produce compared to the other ones. Just a grove done by the router to accomendate the pvc pipe and the carbon reinforcement.
To cut it out I just angle the blade of the jigsaw at 45° and cut an oval. As I cut through the pipe twice it just have to line up.
The sawblade takes away about 2 mm of the material, hence there is some play. I have put a layer of 450 gram glasfibre to come back to the thickness. I will test tomrrow. Maybe more is needed. We will see.
I also made a finger hole with a bit of Tufnol for fun and to make it look nice and to be kind to my finger.
