Laser exhaust air diffuser

This is an air diffuser to help equally distribute air from a 4" inlet across the engraving bed. The hope is it will reduce vortices and direct air across the working area straight towards the exhaust.

Note: Your enclosure does need to be sealed so that air is only brought in through this one intake.

I have a Snapmaker so this is 320mm wide.
Not hard to print but it will need some supports in the center.
