This is my first print on my new Anet A8! So the quality may not be the best.
BUT: the forefront is horizontal at the bottom, so this seems to be difficult to print because the printe has to print a layer in mid air...
Not so bad for a first print ^^
You have to create "supports" for the mid air layers (an option in your soft) and a ring fan duct like that will help you for that kind of problem ^^
Thanks for the picture ^^
Thanks for that hint! Oh and by the way: You should make the bottom layer thicker. There is barely any material at the bottom...
But the cooling seems to work ;) And the falcon is flying all the time! :D
