1piece High Temperature Sharp Hardened Tool Steel MK8 Nozzles 0.4mm for 1.75mm Makerbot, Creality CR-10 All Metal Hotend, Ender 3/ Ender3 pro, CraftBot, Prusa i3 3D Printer

Does what its supposed to do.

With the original ender 3d printer ....its a must have upgrade

I got these nozzles to print some carbon-fiber-impregnated filament, since theyre hard enough to not be worn out by the embedded fibers. I put one of them in the printer, leveled the bed, and did a print with regular PLA. The quality (with the exact same settings) was noticeably poorer, with a rough finish. The nozzle seemed to do some kind of weird dribble with the filament, instead of letting it come out in a smooth stream. I slowed the print speed down and the dribbling effect was less severe. However, I was able to easily crush the printed object in my hand, where the same print with the brass nozzle was strong enough that I could barely bend it. I tried a few other prints and wasnt able to get decent print quality. Thinking I may have messed up my printer somehow, I put the brass nozzle back in and leveled the bed. Its printing with that nozzle right now, and the quality of the print looks good. Filament is flowing smoothly, and the print doesnt have a bunch of weird little boogers and other crap on it like it did using the hardened nozzle. I may be doing something incorrectly, but I dont know what that might be.

Yuk!! Great for glow in the dark filament. But using stander filaments started to clog. End up replace original nozzle.

Perfect with carbon fiber PLA. Printing impact resistant stuff easily with no noticeable wear. Ill keep an eye on it so stay tuned.

Quick delivery. Have to wait on a new hotend to try it out. Was getting horrible prints but I now do not think it’s the nozzle.

Worked well for Glow in the Dark filament so far. Im constantly printing so well see how long it lasts

I could not get this nozzle to work well on my Ender 3 Pro. Please keep in mind maybe i am doing it wrong. However i used other nozzles on my printers perfectly fine. But this one would not print right, I think I got the wrong size! It looks smaller than my usual 0.4 Nozzles. Perhaps this is why. It also leaked on me alot.

I believe the price I paid was fair, but according to the picture in the description of the item, it was stored in a plastic container. When I received my item it was in a small plastic bag which was put into a very big bag mailed to me.

Nice price
