[Lab] Laser cutter venting

[Darcy Whyte]

But if the dryer is running then laser fan has to move more air than the
dryer or the dryer exhaust will go in your machine.

And if the fans not running then the drag it causes will also cause dryer
exhaust to go in your machine.

It's so easy to add a plate into a window with a hole for the exhaust
hose...
