Sharing a ventilator idea.
This uses a Braun replacement motor & blade from a bathroom exaust fan ($19 at the big box store).
It sits on top of the enclosure and pulls air through the logo cutouts. I fabricated this one from aluminum to get the weight down by my first pass was made with wood/mdf. Since my shop is in the basement, it was easy to rig a pully overhead to hoist it up and out of the way when not using it. It turned out to be a nice ventilator for soldering too.
How are you ventilating yours?
