Basically redesigned the whole thing to be more robust.
The nuts fall out of the original making installation a pain.
Added Fillets to edges for cleaner part.
A notch is needed to avoid removing the upper support screws to install.
Built to match a real 2020 extrusion instead what looked like a guess.
Provided all the SolidWorks files so others can make their own mods.
I hate it when only partial files are provided making the design useless to others.
Included the assembly as well.
