First, it is very hard to read the stamped sizes on the nozzles. Most are VERY faint and you need a good light at an angle to read it. Second, most of the nozzles are .4. I bought this set to get a few .5 nozzles to install on my MK8 extruder. I have never had so many extruder jams. (In fact, almost never have extruder jams) Yes, I know how to install a nozzle properly on a MK8 extruder. I tried 2 of the .5 nozzles and both jammed up after not many hours of printing. I reinstalled an older .4 nozzle that I had and the problems went away.I can't say that everyone will have problems with these nozzles, but I did.If this review has helped you, please click on the "Helpful" button below.

I pushed 75 kilos of ABS through my printer's original nozzle. At one time the orifice was all distorted, so I filled it with solder, and used a micro-drill to put a new 0.4mm hole through that..I been meaning to buy new ones, but the ones for my printer seem overpriced. These seemed wonderful. I was gambling that they might work, and today they arrived.The nozzles have identical outside dimensions and threads, but the interior hole on these is too small to fit onto my extruder.So, all I did was chuck a nozzle into my drill, and then grabbed a 9/64 drill bit in a vice grips. Then push the spinning nozzle against it. The hole will automatically center itself.Drill the hole at least 0.3 inch (7.62 mm) deep.Success on the first try. It's actually pretty easy.. I'm very happy, so why not give it 5 stars.

I print a lot with my CR-10 and definitely was in the market for new, inexpensive nozzles. This is not only exactly what I needed but a gorgeous assortment of nozzles that fit right on my CR-10 and give me the prints I need. I literally don't have to worry about getting nozzles anymore as this is a very affordable bundle that allows me to print in all kinds of layer height. This was one of my better purchases for my CR-10 and I love that this bundle existed!

Fits perfectly in my ender 3 and because they are such a fine point it increased the print quality. Switched to a .6mm and saved so much time off of all my prints. Great price, variety, and quality.

i have used 3 nozzles so far with no issues ( i change them out after a few weeks of printing. just my preference not because of any issues)

I ran through several of these in most sizes before upgrading to an E3DV6 hot-end and didnt have any issues.

They screw in and squirt plastic. No burrs or manufacturing defects, they just work

These might be fine for most printers, but for my Creality CR10S Pro with the original hot end, they don't fit.
