SummaryThis is the newest version of the cooling duct for a FlexMendel printer. The vents now have a more centralized flow aimed towards the tip of the nozzle. Both vents have been adjusted so the fit together with 3-4 screws. This model has a lot more rigidity and allows for better flow. Print SettingsPrinter: FlexMendelRafts: Doesn't MatterSupports: YesResolution: 200 micronsInfill: 90%Notes: The first vent should be printed using support material. Set the overhang threshold in slic3r to 15 degrees so it does not include any unwanted support. The second vent can be printed without support material. Make sure your printer is first capable of printing this low overhang angle (it's about 25-30 degrees).
