DIY Meets High End Fume Extractor for Laser Engraving/Cutting

In this video, I show the first (not so good) fume extractor I made and why it didn't work. I also show the much-improved fume extractor and some tips if you decide to make your own filter. It is a mash-up of a DIY using off the shelf components by respected companies in the industry. ======= Compenents: Bofa AD350 Filter - https://www.matterhackers.com/store/l...
