Laser-etching

For the insert in my USB stick I had to learn the best method to use the laser-etching material. The first few attempts went wrong as I had the laser settings too low. Then after a few attempts of getting better I realized that my design wouldn't etch as a thin area of material to be left un-etched was too thin and it was just etched over. This led to the design having to be changed to this

These are images of me getting to grips with it.
