ToiletTron2000 Miniature Blower Duct for Geeetech Mizar Series printers

(Original design from here: https://cults3d.com/:1323209)

This is a re-work of the “Creality Ender 3/3Pro Part Cooling Fan Duct” by KingYS

Significant effort was made to re-shape this and rework the mount to be compatible with the Mizar S while avoiding geometry errors during the process and while maintaining the same level of airflow (read: it sucks as of v1.0 lol).

Yeah I wouldn't recommend this over the stock blower - again not as of v1.0, but you may wish to modify this to your liking. I intend on investigating the design to see if significant improvements could be made without compromising the compatibility with the stock hotend shroud.

No supports required. I used 10% Gyroid infill, and used Overture PETG though I'm sure PLA would be fine. Uses the original Mizar S screws, so no extra hardware needed. 

Super good upside: v1.0 uses a whopping 5 grams of plastic. It's basically free apart from the 30 minutes of print time you'll waste printing this thing.
