Lincoln Electric Miniflex Fume extractor nozzle

My Lincoln Electric Miniflex Fume extractor didn't come with a nozzle for it and it's stupid expensive. Rather than fork over the cash, I decided to model this thing up. It works well but definitely print it out of something FR (flame resistant). I used PLA since I'm only using this for TIG- print it out of something strong if using for MIG or stick welding. I used a standard round magnet that I found at the hardware store.
