THIS IS A SCREEN NOT A SHIELD - ALWAYS WEAR GOGGLES AROUND YOUR LASER CUTTER/ENGRAVER

This screen is intended to provide some small protection when the laser is active and you are some distance away (e.g. working on a computer on the other side of the room but casually glancing in the direction of the laser). It is not an enclosure or shield that blocks the laser from all directions; goggles must be worn whenever using a laser cutter or engraver.

The screen is appropriately tinted plastic sheeting cut to the required size. The parts here are the structure that holds the screen together. There are many vendors of inexpensive plastic sheeting cut to size.

I use this screen with a Creality 10W Laser Module attached to my Ender-3 V2 Neo 3D printer.
