If you're tired of super sophisticated fan ducts that work well but obstruct the nozzle from view an hex wrench this might be something for you.
And if you're trying to slim your extruder this will be a cut-down of -30g in weight compared to the stock fan duct. In an attempt to save weight I've also improved the aerodynamics a bit.
That's it. It's just a slightly improved stock fan duct that will fit your original 40mm fan and screws.

Use of a material that can stand some heat (ABS, PETG, PC, HT-PLA,...) is recommended. I used Extrudr greentech. Also consider an upright printing position for better overhangs.
