Anet a8 Double fan duct with stock fans

thingiverse

I'm a bit of a novice when it comes to 3D modeling, so don't expect too much from this project. This double fan duct only works with the specific bowden mount (https://www.thingiverse.com/thing:2193695). To build this duct, you'll need: * Four M3 or M4 nuts and bolts to secure the fans * Two 50mm fans, similar to those that come with your printer The fans I used produced a lot of vibration, but fortunately, they didn't negatively impact print quality. I performed a 2cm to 11cm bridge test at 60mm/s with the fans running at maximum speed, and the results were quite good. For comparison, I also ran a test with the fans set to 50% (check the photos). The fan duct I modified is available here: https://www.thingiverse.com/thing:2305368
