Fan Duct 120 mm - Carbon filtering

Housing for a 120 mm fan with an easy to exchange holder for a carbon filter.
I use two of them in my airbrush/soldering cabin.
Easy to print with no support. Both parts need to be glued together with some CA or hot glue, duct tape also works fine.
As filter material I use active carbon mat for hoods, trimmed to size such as: https://www.amazon.de/H-24-Filter-Dunstabzugshaube-Aktivkohle-zuschneidbar/dp/B01N1KTWD5/ref=sr_1_2?hvadid=80058222021784&hvbmt=bp&hvdev=c&hvqmt=p&keywords=m%26h-24+filter&qid=1577610330&sr=8-2
It works also in 3D Printer housings to reduce the fume of for example ABS prints.
