I engraved many charger adapters using my OG F1 and I needed the same settings for my F2 Ultra, here they are! In this case I picked the Rammstein logo from their wikipedia page but you can replace by any logo or text of your own choosing! The result is a very slightly textured (barely noticeable to the touch) gray that contrasts nicely with the white of the material. Never lose your adapter ever again!
When the laser job is done, open the enclosure and enjoy your freshly customised power adapter, no need to wipe anything off the product!
