Adapter for 120mm fan to 4 inch duct
prusaprinters
This 3D design offers a solution to connect a 120mm fan to a resin 3D printer enclosure, facilitating the extraction of off-gasses from UV resin printing. Designed for a 120mm fan to fit a standard 4-inch duct (Dryer Duct), ensuring airflow. Its construction ensures no support needed and easy printing. It can be placed in the middle of the duct or inside the enclosure. I added 4 holes to add zip ties or bolts to hold the assembly.By directing harmful emissions to a vent in the wall, this adapter contributes to a safer and healthier workspace, mitigating the risk of exposure to harmful fumes.I used a High static pressure fan like the one in the picture.I used PLA+ and no supports with a 0.2mm layer height. UPDATE: I initially described this model as created for a 140mm fan size, however it is for 120mm fans. Thx to @AustinBland_2036568 for the comment and make :)UPDATE 2: if you scale this model to 116.67% you can fit a 140mm fan.
