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

Just another bronze nozzle with an easy to remove coating

The threads are WAY too short to work for a Prusa i3 MK3s. The heater block will have to thread in so far that your carriage WILL melt.

Carbon fiber filled PLA is abrasive and wears out normal nozzles this one provides some resistance to the wear.

I received a nozzle with 3 dots on it like the listing says for the .4mm. However the nozzle is far smaller than even my .2mm nozzles. I didnt notice and ended up having to spend a long time unclogging my machine. Im going to shop on ebay for now on for nozzles since this isnt the first time I received the wrong size.

Good clean prints so far with initial testing. Bump your temps up 5-7 degrees across the board though. I had multiple prints fail after the 3rd or 4th layer due to filament backing up in the nozzle. Higher temps were an easy fix.

Great for high temp printing on those touched filaments like wood, metal infused, and harder plastics

I put quite a bit of carbon fiber filament through this nozzle, and it still prints like the first time! Excellent nozzle I highly recommend it!

The first minute or two comes out fine, but then it just stops. I dont know if its because the nozzle isnt optimize to hold heat, our maybe printing PLA over 220°C+ isnt enough. This review wants me to address sheerness whatever that means, but I cant really give an answer on that if I cant get a print at all.

Pretty good, just sucks you cant tell what size it is bc there no ingrained on it

Fits perfect. Easy to install. Quality is top notch, very durable. Cant do much better for a nozzle that will last a long time.
