Instructions
Make sure that the notches in the design match your material's thickness, then cut. I set the wave to be rgb #ff0000 and the stand shape to be #000000, which your print driver should allow you to customize. The wave's shape is a vector shape, so no bitmap engraving should be necessary.
If you can figure out how to intersect the two shapes correctly so that the laser doesn't spend time engraving outside the actual shields' areas, I'd love to know how (-:
