Because i liked the original duct from CodeMonkeyZero i designed a cover for the hotend fan.
I'm using a Noctua 4020 as hotend fan and so the fan looked a little bit outside the duct.
Also my Kids are playing araound and i don't wanna an open fan at the front.
Its easy to print upside down.
I used PLA+ with 0.2mm layer hight and a 0.4mm noozle at 100mm/s printing speed. 18% infill is enough. With this the printing time was ~25min.
The author remixed this model.
