CNC Eye Protection for laser engraving ( 1610 / 2418 / 3018 )

I created this thing with Tinkercad to attach to my CNC Fan Mount
https://www.thingiverse.com/thing:2954044
to provide some basic protection for nearby eyes whilst engraving. As stated in the Fan Mount thing I believe the X-Z carriage for all the machines listed are the same so it should fit them - the pictures here are on my 3018 and most were taken during engraving.
