NOTE: This is just a rough template, expect to have to do your own hand shaping/fitting.
The baffle template is too big to fit onto a single sheet of paper. You will need to print both parts at 1:1 scale, cut them along the marked center line, then tape them together. At that point you can cut it out and use it as a template:
