Anet A8 fan duct hybrid

V2.0 (2017-11-04) Simply added a schematic to visualize the difference between 20mm and 22mm heights. Last week I printed only with this duct, and I'm extremely satisfied. V2.0 (2017-10-07) I completely redesigned the fan duct, and now it functions exactly as I envisioned. Improvements over the old version: The old version is included in a zip file for reference. - Easier to print - Larger tube - Better airflow at all holes - Beveled corners optimize airflow and reduce resistance - Improved blower connector ("disabled" the whistle sound; now it rushes only) - Better grip on the blower I added two versions with different distances from the blower bottom and duct bottom (20mm and 22mm). The 20mm version has more clearance to the print bed, while the 22mm is 2mm lower. It works incredibly well for me right now. Please let me know if it also works for you. V1.0 (2017-09-27) (First and old version) This design combines elements from https://www.thingiverse.com/thing:2186878 and https://www.thingiverse.com/thing:2234778. I loved the larger holes and compact design of the first one, as well as the nearly full circular airflow from almost all directions in the second. So I designed a combined fan duct that fits perfectly into my blower with the nozzle in the middle. I'm also satisfied with the relative height to the nozzle. Some ducts are very far down, so they scratched the first tracks partly on the glass plate. 2017-10-02 IMPORTANT: Actually, I am testing a new design. If it works as I imagine it, I will update this description and replace the files. At the moment, it looks good. The new one is slightly bigger, but very light, and the blower is significantly quieter (it used to whistle).
