Elegoo Neptune 3 Hotend Duct

I designed this hotend cooling fan duct for the Elegoo Neptune 3 series (Pro, Plus, and Max) as a recreation of the original factory part.

This model is a direct replacement in case the original part breaks, gets lost, or you simply need a spare. It fits perfectly and is designed to the same specifications as the stock part.

Required Hardware:

The same screws and fan that came with the printer are used.

                                            How to print it correctly:

🔹Layer Height → 0.2 mm

🔹speed → 40-70 mm/s

🔹Smoothing mode

     |→ Smoothing pattern: zigzag

🔹Count of wall lines → 3

🔹line width → 0.42 mm

🔹supports

     |→ To add supports → Generate supports everywhere

🔹Support pattern → zigzag

     |→support density → 30%

🔹Enable support interface

     |→Enable support roof

     |→ Support roof density → 60%

🔹adaptive layer height → 0.1mm

🔹Ironing mode

     |→ roning pattern → zigzag

                                        How to assemble the part

total parts: 

🔹6 black phillips-head screws (3 per fan)

🔹4 phillips-head screws to secure the bracket to the extruder carriage

🔹2 allen screws to fasten the complete extruder.

First step, remove the 2 allen screws with an allen key

Second step, disconnect the fan cables from both sides (2 cables with 2 pins each)

Third step, remove the 4 phillips-head screws that hold the extruder carriage bracket.

Fourth step, remove the bracket from the extruder carriage and take out the 3 black phillips-head screws on each fan (one of the screws on each fan is on the other side, and make sure the arrow is pointing downwards to push the air down).
