thingiverse

This is a mount to attach AC Infinity 120x38mm fan on a standard 4" duct hose (and for venting to the outside through a window). Tested with followings. - [AC Infinity Fan AXIAL HS1238A](https://www.acinfinity.com/component-cooling/axial-fans/115v-ac-axial-hs1238a-muffin-fan-120mm-x-38mm-high-speed/) - [AC Infinity 4" duct hose.](https://www.acinfinity.com/hvac-home-ventilation/ducting-clamps-grilles/ac-infinity-flexible-four-layer-ducting-8-ft-long-4-inch/) - [AC Infinity Fan Speed Controller](https://www.acinfinity.com/component-cooling/axial-ac-fan-kits/fan-speed-controller-for-ac-axial-muffin-fans-single/) For easier remix, I'm posting STEP files as well. Enjoy! Usage ===== To put the fan in the middle of duct hose, please use these two. - AC1238 S : hose to fan, i.e. hose increaser - AC1238 RS. fan to hose (again), i.e. hose reducer To put the fan on the window, please use these two. - AC1238 S : hose to fan, i.e. hose increaser - AC1238 RW. fan to window (just a mount) Please note, window mount is probably compatible only with relatively new houses in USA, i.e. window frame's height is 1171mm and thickness is 32mm. For other type of windows, please feel free to remix:) Rerefences ========= [GUIDE: How to get water and airtight prints...](https://forum.prusaprinters.org/forum/original-prusa-i3-mk3s-mk3-general-discussion-announcements-and-releases/guide-how-to-get-water-and-airtight-prints-on-the-first-try-with-just-2-perimeters-and-the-default-0-4mm-nozzle/)
