I've come back to this old post. I know somebody tried to model it previously, but I don't believe they got it right. This is what I get in profile, which I think looks far more what the original designer was looking at.

The original drawing shows it in 3/16" steel. If I wanted to go for aluminium, as per the Savvy slider what thickness would be reasonable? Or put another way, how thick is the aluminium part of the Savvy slider?
I do know that the bends could not be sharp as shown above and would need a minium radius, but I am not a CAD expert and have very baic tools, so have ignored that for simplicity at this stage.
