### If you use this fan duct & think it makes your prints look better, don't forget to TIP! ;)
## The story
I designed this fan duct as a 100% free & open source alternative to another one which was very good, but unfortunately it's license was preventing me from modifying it the way I see fit & share it freely.
So I started Blender, and made my own from scratch in a couple of days. One that I can share freely with the community, so anyone can use it, remix it or trash it - in any order ;)
The fan duct works very good for me, but I give you no warranty that it will work for you.
## Highlights of this fan duct:
- The most important: it's more effective compared to the semi-circular design, and A LOT more effective than the stock Anet A8 fan duct.
- it's quieter, compared to the stock & the semi circular design
- it does not block the view, and you can see your nozzle tip
- it uses my own attachment design, and once it's inserted onto the fan, it's impossible to fall off. Forget about the tape or glue for securing your "always falling" fan duct.
- it blows more air, compared to the other duct designs I tested. Instead of concentrating "on the tip of the nozzle", the air flow is wider, and separated at 2 flows at approximately 90 degrees. This way it cools wider area, even if the nozzle moves away from the "point of interest".
- when mounted & tuned properly using PID Auto Tune (described below), it does not cool the heat block, and the temperature is very stable…
