Noctua 120mm fan box for exhaust duct

This is a box for Noctua (but maybe also other vendor) 120mm fans.The fan box can be used with 10cm (4inch) hose to send fumes out of the window.The Noctua NF-F12 iPPC-3000 fits perfectly.If you need to install the box to the wall, there is a mount kit with anti-vibration system (to be printed in TPU). You need to cut anti-vibration pieces according to your needs.You should buy nuts and bolts according to your setup. I used M4x40mm for the box and M6x45mm for wall support. Washers suggested
