superficial tweaks as the original works well but i wanted to beef up the face, screw tabs and end portion where you screw the bracket in place.
I also included a cutoff for link light activity.
I placed the object on the thin edge opposite the screw tabs and used brim and organic(tree) support for the tabs for printing.
