Upgrade 3D Printer Extruder Hotend with 0.4mm Nozzle - Compatible with Creality CR-6 SE, Ender 3, CR-10 Series | Perfect for High-Precision Printing, DIY Projects & Home Use

This was exactly what I had envisioned an Extruder Hotend should be. Incredible air flow which is the key to success. 2mm screws might scare you but don't be, they are all it needs. This is solid even as fragile as it looks. Don't be deceived though because this unit is a workhorse. I was working on building a new style Fan Duct system for my Rail Modified Ender 3 Pro. This extruder was the perfect match. I attached pictures of my creation. Has 2 dedicated Noctua 4020's for parts blowers, A 60mm on a 45 degree tube blowing into another 4020 Noctua blowing on the extruder. I am running my printer at 140 percent on speed and this Extruder Hotend has no problem keeping up. This is the only Extruder Hotend I will ever buy again.
