Anycubic i3 Mega Circular Fan for Large Fan Ducts

thingiverse

Three upgraded circular clip-on fan designs for the Anycubic i3 Mega with expanded fan ducts that won't fit mileshkin's original design. Versions: * 24 holes: Lower airspeed * 12 holes: Greater airspeed * Airblade: A sleek design that is a challenge to print without getting supports stuck in it If you find an easy way to print the Airblade version, send me a message and let me know. UPDATE 30-Oct-2018: The improvements have been expanded to the Airblade version, which can now be carefully printed right side up with delicate supports under the upper edge of the airblade. Still quite a challenge! UPDATE 29-Oct-2018: Further enhancements were made to airflow and printability. A big "Thank you!" goes out to Trayal and mherwigDE for their valuable observations and criticism. The part now prints without supports for the ring! Also, airflow is directed further downwards onto the print, rather than the nozzle. Airflow is spread across all holes a lot more evenly than before. I also encountered problems with the roof of the ring using the newest 3.5.1 version of Cura. For some reason it was trying to start bridges in mid-air instead of on top of a wall. I got around this by setting the wall line count to "1". This made no real changes to the way this was printed with a 0.4 mm nozzle and placed the bridges in the right place again for proper printing. UPDATE 07-Sep-2018: All versions have been updated and further improved. Airflow is now more evenly distributed and structures easier to print.
