Thanx crisis time,
thanx Terry,
the real seal is a 4mm seal in H-format
***Click here***. The shop also offers 2,5mm thick seals, but they are too small. My cabine is 1,5mm thick and the 2,5mm seal only works up to 1mm thickness of the window frame.
The fake seal is a 0,5 Millimeter thick frame of styrene painted black with an edding and glued on the CD cover piece.
But this is only a test, the final window will be made of clear styrene (1 Millimetre) and a 0,5 Millimetre styrene frame. On the clear styrene my glue will hold the frame.
The CD cover plastic does not react on the glue.
