And an easy changeable Nozzle duct.<br>And i did not like to buy new parts - so you do not need anything else then you already have on your printer.<br>If you want go improve the screws you can go for thread inserts. Which i melt into the part with my soldering iron. In the beginning I just did the holes 2.5mm without inserts - works fine as well.<br>But it works fine as well if you just screw the original screws into the 3D printed parts.<br>A big advantage is that the flow of the hotend cooling is going straight to the hotend and is not affecting the nozzle cooling. The print results are improved!<br>The Duct and the hotend cooling are CFD flow optimized.</p><p>You can use the original fans and screws - no need to buy new parts.<br>To make it perfect use M3 inserts otherwise use the stl files with "screws" in the filename.</p><h3>Print instructions</h3><h3>Print Settings</h3><p><strong>Printer Brand:</strong> Anycubic</p><p><strong>Printer:</strong> All-metal Mega</p><p><strong>Rafts:</strong> Doesn't Matter</p><p><strong>Supports:</strong> Yes</p><p><strong>Resolution:</strong> 0.2</p><p><strong>Infill:</strong> 25%</p><p><strong>Filament:</strong> <a href="http://www.amazon.com/s?url=search-alias&amp;field-keywords=Extrudr+PLA&amp;tag=tv-auto-20">Extrudr PLA </a>Black<br><strong>Notes:</strong></p><p>I used Extrudr PLA and ASA for the duct.
