Re-uploaded, and improved. Not designed to extract air of 3Dprinter enclosure. I got a really serious problem of particles in my workshop an this is designed to take a high air flow and clean it, if you try use a 120mm diameter for recycling or extract air on little 3d printer probably you can't control the temperature. Included universal 120mm bracket for easy place whatever you want, no matters the thickness of the fan you have, Included 2 types of exhaust: -The shortest is just to avoid air fluctuations around the fan, getting more pressure inside the filter. -The large is to join whit 120mm duct. Retain plate M3 screws Fan joints M4 screws Bracket plate M5 screws Uses Roomba 800-900 series filters. This assemble is designed to work with high pressure 120mm fans, like top end sunnon or delta, Regular 120mm fans will work, but when you have a filter, the main fact is the pressure of fan to avoid the throw-down of the flux when the filter starts get stuck. Coming soon i will make another design whit 2 filters the same, but for 80mm fans, probably whit the coupler to stack fans in series and increase the pressure of the system. 80mm cheap fan, whit low pressure is enough for a 3d printer enclosure, and the dual filter gives you long time between replace filters. Just wait some days, if you want it to place on 3d printer enclosure 80mm Filter: https://www.thingiverse.com/thing:4211829 80mm Butterfly valve: https://www.thingiverse.com/thing:4216080
