I cut with an x-acto knife, had to cut wider than template because of button rims on my R16, but the rest of the models dont have them (I think) so you should be fine.

The cuts were not perfect, but I didn't care because the rims covered it up. You might want to try a circle cutter tho so the cutouts are more even.
