FLSUN QQS Pro Vortex Part Fan Duct for Volcano Hotend

thingiverse

This is a modified and extended version of the original part fan ducts off the QQ-S Pro for use with the Volcano Hotend. I couldn't find anything that cleared the Z-Probe magnet extender so I modified the original. This design fits much better than the original and prevents air from flowing past the duct at the top of the effector by use of a small lip. The internal cavity compresses air towards the tip which includes 6 offset airfoils to create vortices as the air exists the duct. They are designed to set as close to the part as possible and eliminate any unintended cooling of the Hotend. This part is thicker than the original and I widened the tabs to ensure zero play and a nice lock fit into the aluminum effector slots. This can be printed as imported and need no supports, just a wide outside brim for adhesion. It's optimized for 0.4mm or 0.8mm nozzles. This single file is for both the left and right fan ducts. I've included the STEP file incase anyone needs to modify.
