A few months ago I started using 3D scanner for making matrices. If anyone is interested I can make a 3D model of the deflector in-channal. If you have the technology of production. I can contact the manufacturer with whom I WORK and make this model, but it is necessary to prepay 100 models and the matrix will remain with the manufacturer, this preliminary information. There are also difficulties: acrylic. The manufacturer uses to 2 mm acrylic. In the channel of 1-1.5 mm. In Russia such acrylic hard to find. Probably will not even engage. You can contact the WeatherTech and invite them to the 3D model, and they do this quickly. Need a CNC router that will engrave the prototype matrix and make you model
