We have made this panel for our Iveco. The panel itself is rather soft and flexible, making it not really easy. You could of course also take over the contours on a wooden panel. But because we made this for ourselves, we thought let’s take on the challenge. In the end, the diamonds will only become really tight when the panel is mounted on the steel partition. That is precisely because of its flexibility. If you want a tight panel from the start, make a wooden one.
The subtitle in the video is also the explanation. You can turn it on at the bottom right of the video.
