iMetrx 8PCS MK8 Nozzles 0.4MM,Hardened Steel Nozzles+Stainless Steel Cleaning Kit,Hotend Extruder Nozzle for Makerbot Creality Ender 3 3D Printer.

Unfortunately I could not get these to work well with my Artillery Sidewinder X1 printer. I've not been able to find the exact reason for them printing messy, wiry and fluffy, but after replacing with a normal brass nozzle, the printer is once again working well.

Don't use or buy these, especially for creality printers , these don't fit correctly and will ruin the hot end , these also require and extra 20 degrees in heat than a normal nozzle just so they sort of work. Don't bother with these your be disappointed and will have to buy another brand

The hardened steel nozzels in this kit are infact plated copper other than that the rest of the quality seams fine

Unfortunately on my first attempt to use these on my ender 3 v2 failed, not because I don't _have_ the right tools, but because potentially they don't exist. I have nozzle hex spanners in 6, 7 and 8mm, but none of them remotely fit. I think the size you need is 6.5 or maybe not even that. I assume you can get 6.5 hex sockets but none of my sets seem to jump in half millimeters.They certainly look nice, but at the moment because time is of the essence and this being frustrating when you're in the middle of doing it, I've had to put a stainless nozzle on instead as I don't have the right spanner for this and I'm now printing glow in the dark with that. So be warned, and come armed with an adjustable wrench rather than a spanner.Oh also...honestly, I think I'd rather ruin a nozzle than deal with the issues you get when you use steel instead of brass. Clog-tastic. :/

All the same size so no having to check nozzle size, These .4mm I used ABS and nozzle fan 100%.Work very well but then I did a heat tower first.Ok down to the Surprise, I thought was going to just be Nozzles, ok I hear you say ! Heat tower every new Roll of filament , Even new nozzles too, and you won't need these a set of Needle files &Needle means Needle. Superb set for removing stuck Filament. And if not careful a groove in the Nozzle. I use Open 3D and closed FDM I have 7 I'm Testing and just love this set. Thankyou for letting me Test . Guys you get a Fantastic set and Superb Value for your Money . Have done 3D for 3 Years so not a novice. But learning all the time.

These are my first try with steel nozzles. I've always used brass ones in the past and just replaced them when they wear out or get clogged. Fitting them was just as easy as fitting a brass one, levelled the bed (yet again), and started printing with some slightly abrasive filament that tend to wear through brass nozzles after a while. I probably haven't been printing with it long enough to tell if it's more wear resistant (but I do believe it will be), but what I can say is that the print quality look great and I'm very pleased with the results.

I decided to give these a try after my other steel nozzles was causing blockages after blockages.I've been using these for about a week now and had no issues whatsoever with them as regards to blockages.My prints come out super clean with no stringing when using PETG.These steel nozzles are a must if you are printing in PETG because the filament doesn't stick to the steel as much as brass.Considering these are half the price of one Nozzle X they are worth every penny.These are now my go to brand of nozzles for all my 3D Printers.

Nicely made nozzles without any visible burrs. As normal but needs a couple degrees hotter than brass.
