<h1> Update: 2021-02-19</h1> * Found an error on the E3D Version, when reprinting the duct for myself * deleted the faulty version and uploaded the corrected one <h1> Update: 2021-01-16</h1> * Finished the Support Free Version * Made a Version for an E3Dv6 Hotend * Made CFD Simulations for all Versions * Renamed the STL's <h1>Update: 2020-12-21</h1> Redesign of Variant 1 (FLSun QQ-S Pro Duct v4): * Better Fit and Snap * 1mm "Ring" to better cover the printers opening * Nozzle better centered * Airflow optimized <hr> Most of the existing designs were not quite OK for my Stock QQ-S Pro. Almost all (I tried) where blowing directly onto the nozzle. Compared to the stock duct you might need to decrease your fan-speed. PID Tuning after replacement is recommended. I recommend using PETG or ABS for printing. After serval testprints I finally used GreenTEC Pro from extrudr (it prints almost like PLA using temps like PETG, but it is Heat resistance up to 160°C VICAT A / 115°C HDT/B*)
