Circular fan duct for cr-10

thingiverse

I've discovered a common problem with many circular fan ducts - the nozzle often isn't even remotely centered, so I built this one from scratch. To ensure optimal performance, I also designed the interior to cool the filament evenly on all sides. Notably, despite the ring being just 1cm away from the nozzle, I haven't encountered any issues while printing with a 200°C nozzle temperature - although I haven't yet tried higher temperatures.
