## Description

Nozzle size: 0.4mm; Filament size: 1.75mm; Package: 1piece nozzle; Material: Hardened Tool steel; thread: M6 ; Nozzle size with dot: 0.25mm(No dot); 0.4(3 dots); 0.6mm(4dots) ;0.8mm(5dots)

Review: Work flawlessly - Building a fully dynamic F-18E Super Hornet cockpit, wanted to use Carbon Fiber PLA on some of the parts, specifically parts for the landing gear lever. I was having problems pushing it through a .4 nozzle, got the .6 and the .8, they were clearly labeled on the packaging for size, and marked on the nozzle itself. Used the .6, it has worked flawlessly, I can't express what a fantastic nozzle this is, put it on the hotend, leveled the bed, and it laid that carbon fiber PLA down perfectly, and really does still maintain the detail. Couldn't be happier with this nozzle, kudos to them for a fantastic product, I will be stocking up on more from them.
Review: Dimensions on point - Looking forward to running this on my printer. Threw this on measurement equipment at work, the . 4mm nozzle measures out at ~.420mm and the extruder side 1.75mm measures out just under 2mm(1.970mm). Video is focusing down the nozzle after cleaning with air blast, no visible burst or imperfections. Will have to get filament to test the hardness/longevity.

### ⭐⭐⭐⭐⭐ Great Nozzle, but be prepared for higher temps
*by A***R on March 3, 2021*

Took me a few days to dial this nozzle in, but once I did I had no issues whatsoever; I was actually able to get better print quality out of this than a brass nozzle (Managed to pull off some near-SLA quality details on a miniature with the 0.4 mm which is pretty astonishing). That being said, I had to bump my PLA from 205 up to 220, and had to go all the way to 260C for PETG. Works like a charm with the half-kilo or so of carbon fiber PLA I've printed, however. Overall, this is definitely worth the $6 if you're looking to print something more abrasive; just be ready for a big temperature increase.
