Ender 3 Pro Stock Fan Cooling Duct Upgrade

thingiverse

I remixed the settings to match my Ender 3 Pro purchased in December of 2019. You may need to check the original files if your printer requires a second set of tabs. No built-in supports are available, so external support is necessary. I use 10% infill density for printing. To print thin walls successfully, you must enable this feature. I strongly recommend using PETG or ABS as they produce better results. PLA prints will eventually fail, and it's not worth the effort in my opinion. The PETG print shown was printed at a nozzle temperature of 240 degrees Celsius, a bed temperature of 80 degrees Celsius, and a print speed of 40mm per second.
