Flared vents in a configuration very similar to many Gundam chest vents. No background for use with any color, or you can apply a backplate for detail. To create your own backplate, use the tapered rounded corner trapezoid in the second to last row of preset 1 at size 200, 200, angle 270. Alternatively, I have created and share a basic metal and a yellow (255, 200, 0) backplate for use with this decal.
