Quiet Neptune 4 Plus-Max Fanshroud

Original model Elegoo Neptune 4/Pro/Max/Plus Fan Shroud V5 (OrzOrzOrz)

My remix based on the N4-Shroud V6 Prototype, numerous elements have been redesigned.

FanShroud_V1.1 – standard version, FanShroud_V1.1_M – version with mounting for 4x2 mm magnets.

You can use the screws from the original fans to mount all three 5015 fans.

   Compared to the stock fans (4015 x2 and 3010), three 5015 fans are overkill since they push much more air. To further reduce noise, I lowered the model cooling fan speed to about 60% (in the slicer) and the extruder cooling fan speed to 50% (in the printer firmware).

To do this, go to Configuration -> printer.cfg -> find the lines responsible for the extruder cooling and add the line -> fan_speed: 0.5
   But be cautious, don't lower the speed too much as it may result in insufficient cooling and potential fire hazards. Remember, the extruder houses a board with electronic components.

Tip: You can slightly heat the extruder (around 80°C) to activate the cooling fan. Then, add the line, save, and reboot the firmware. After rebooting, the printer will start with the new fan speed and continue cooling the hot extruder. This way, you can clearly hear the difference in fan operation.

The .3MF file has all the parts prepared for printing. All supports for the models are configured. There is also a test to check the tolerance of the fan mounting.

Important! Ensure that bridges are printed in these areas.

   Significant Modifications

Top Section

• Removed ADXL mount
• Reduced plastic for smoother contours (improving aesthetics and ease of filament loading)

Front

• Added studs for fan mounting using stock screws
• Slightly expanded fan mounting area (to accommodate 5015 fans from various manufacturers)
• Rounded the casing
• Removed the lower LED mount

Side

• Added studs for fan mounting using stock screws
• Modified the shape of the holes (for easier printing)
