I lost my flame template for my 40K game a while back and needed to replace it. I had the option to buy a new one, but instead I copied the templates in the back of the main rule book.
The templates were easy to make. I copied the page with the templates on it. After copying them on a color printer, I cut them out with a scissor. I cut out the holes in the center of the templates using an X-acto knife. I had the templates laminated at my local Staples. Then I cut them out leaving a little plastic around the edges of the template, to keep the templates from warping. Done.
