This file as shown on the left of the main photo will allow you to cut and engrave clear acrylic to be used by a LED light base like the one show to the right. Settings to achieve this result will depend on your CO2 laser. If using a diode laser, you may be able to engrave through various methods like painting the acrylic surface black, but you will not be able to cut. Note: the paint method for a diode laser will not give you the same results as seen by a CO2 laser. Enjoy! And don't forget to like and follow!
