I wanted a better looking fan for my Anet A8, so I created this collection of fans. Since my hot-end is aligned towards the rear of the printer, I decided to design to optional versions, that go off center, so the hot-end body can get enough space from the ring.
There are a circular and semi circular basic versions that are centered on the hot-end, as well as two other versions of the circular design with 2.5 mm and 5 mm offset respectively.
I liked the way mr2webs Anet A3S fan duct looked, so I took a bit of inspiration from his design: https://www.thingiverse.com/thing:2284803
