Air assist nozzle / How diameter

You are all great people. But let’s Focus on the Air Nozzle. I found this here on thingiverse: Twotrees Totem S Air Assist, no glue, no screws by DrSchaumi - Thingiverse
It seems to obstruct the Red Cross laser, which I use to trace my work before Engraving or cutting.
Never printed it but What do you think of it? is it worth printing it? or altering it? Best Regards Patrick
