While I was looking for suitable styrene profiles for the corrugation, I had a quite simple idea how to shape the trapezoids myself. I made a little jig from an U-shaped brass profile …
… that is how it works: I cut a 2 x 5 mm styrene strip, put it into the jig and hold it in place with the little brass bar you can see in the pic above.
Then I scrape off the plastic until it is flush with the jig. After turning the styrene strip around and doing the other side I only have to sand it to get a perfectly shaped strip for the currugation.
Simple solution – wonder why it took me several days to figure that out.
