Help with Trail going through whole Part

Hello devforum, I have a bit of a problem with trying to make a shadow effect of a part’s recent movements, or in hopefully easier terms ‘I’m trying to make a trail but for it go behind the whole object, and not just one thin strip’ and the issue I have is I can’t seem to be able to do that.
This images shows how I want it to look (like the part’s shadow’s movements)

I have tried using the width scale tool on the trail tool to make it wider, however that doesn’t change it in the direction I want…
Any help would be greatly appreciated and I’ll answer any questions I can down below.
