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

Used for Ender 3 pro. It does the job for glow in the dark filament.

I bought this less than a week ago, I got through 4ish prints and started getting all messed up on every job, thought the bed wasnt level, re-leveled, did everything else, then I changed the nozzle to a brass one and have had 0 issues

Good nozzle. Prints as it should. No complaints

Great upgrade for my CR10S.

I recently purchased this nozzle with the intent of using it for printing heavier materials and lasting longer, which I believe is what draw a lot of others to this nozzle. When using regular brass nozzles, heavier materials such as carbon fiber and wood will wear the nozzle down more rapidly to the point where you will likely need to replace it often (roughly every 1-4 weeks depending on how frequently you print). The drawback to going with a steel nozzle is that you will usually need to adjust your print temperatures by roughly 10c to be able to print with the same materials. Unfortunately, increasing temperature 15c or even 20c wasnt enough to work in this case, even on a fully upgraded CR10. When the material was starting to come out evenly, my extruder (a BMG) was having difficulty pushing materials through, often causing them to get backed up and my extruder to slowly give out. I practically had to push the door in firmly and hold it in to put enough pressure on it to push the material though evenly. I will state though that when I switched to regular PLA it seemed to work pretty well with no issues, but if you arent able to print tougher materials easily then whats the point of purchasing this item? That point more or less undermines one of the main purposes of upgrading to a steel nozzle, though I would imagine that it would at least last a bit longer than a brass nozzle for printing regular PLA. Overall Id give this a 2.5, rounded up to a 3.

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.

works great

I am not an expert, but I bought this for printing wood PLA and it just does that.

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

Junk. Keeps clogging no matter what material or setting I tried..tossed it. Lesson learned. Update 2/8/21 .. so after some more testing(Im a noob), and after I stopped whining.. I have managed to get some pretty good prints with this nozzle. Ive only used it with TPU filament thus far, but bought with intent to use carbon fiber through it. In the end, I would say its a good value.
