@ B[x]: I will post a photograph of the vents when the polyestre parts are in place. First I will have to wetsand the lid. I think it will be this weekend. @ derbaum: I could do that, but it would not be as strong as I want it to be. The UHU glue is so much stronger. I tested the resin as a glue and it wasn't as strong as I wanted it to be. Tested the glue and the polyester starts to crack even before the glued parts come lose. It will give the lid extra strenght and stability. When the case is finished I want to be able to take of the entire lid in one piece.
