I needed a spacer for so that my Nilight strobe light would mount flush in the grill screen.  With this I pass the wires through the screen and don't have to drill the screen for the large wire base to pass through.

The customizer will allow you to make any shape with 8 sides(10 sides if you count the top and bottom), and adjust the center hole size and the bolt holes on either end.  The bold holes have the ability to place a nut inside which allows you to bolt the light and spacer together and then with another nut and washer to hold it to the grill.  You can remove the nut indents by making nut size to a negative number. and you can move all three holes to any spacing. To remove center hole set to negative size. To remove end holes set location to large negative number.  Thickness can also be adjusted.
