Needed a vent outlet for creality falcon 2 pro laser engraver/cutter. I just used a hole saw and drilled a hole through the wall in my old shed where the laser is setup. If you need a longer connection tube or something else modified, let me know. I just put this together in Tinkercad pretty quick so not that hard to mod. I recommend you caulk around the tubing during install to seal it up. I also made a removable screen to keep the larger critters out. Depending on your climate and how often you want to re-print this you may use something other than PLA, which is what I used. Pretty straight-forward install. Just like a dryer vent. If you have any questions, let me know. Thankyou.
