Vortex Fan Duct for Anycubic 4Max Pro

thingiverse

The 4Max Pro by Anycubic is a fantastic printer. However it comes with a little spout that blows air from one side of the nozzle. That usually means stringing and sloppy overhangs when the filament leaves the nozzle on the opposite side. This new fan duct is designed to direct air in a vortex pattern around the nozzle's tip. This pattern allows for efficient delivery of air to the print from all sides. Instructions: - Make sure the round heat sink is flat against the carriage as shown in picture. - When print platform is in the Z-home position, measure the distance from the print platform to the bottom of X-axis carriage at the mounting point. Use the 22mm or 24mm design file that is closest to this measured distance. Scale Z-axis by +/- 4% in your slicer if necessary to create a print height that matches your measured distance. On a new 4Max Pro with factory installed nozzle, the distance is 22mm. - Print with material and slicer settings as suggested below. - Attach this fan duct onto carriage with two M3 x 18mm button or cap head screws. - Fasten the screw at the air inlet first. This will snap the fan duct opening into the grooves under the carriage. Suggested settings in Cura: - Use ABS for clean removal of support material. - Infill Pattern = Gyroid. - Support Type = Touch Build Plate. - Support Density = about 10 - 15%. - Support Pattern = Zig Zag. This is easiest and cleanest to remove. We appreciate any feedback to help improve our designs. If you use this design, add this design to your watch list for any updates. Updates: - 2020-04-14 v4: Moved the air pipes lower to prevent air flow from hitting the heat block. - 2019-09-08 v3: I realized v2 was inadvertently mirrored when being exported. V3 should correct this error. Thanks to photo shared by @Marms. - 2019-08-18 v2: Updated design and instructions to accommodate longer distance from nozzle to carriage.
