Protector Aluminium Easy Screen Blade Endcap

Ok, we as makers tend to use products for things other than their intended purpose, in my case, I made a mount for my recovery tracks out of this Easy Screen Blade that I found from Bunnings, but because my use was different from the intended use, the end caps I needed didn't exist, I also failed to find any designs out there, so what was I going to do, make my own of course.
