Aokin 16 Pcs Extruder Nozzles 3D Printer Brass Nozzles for E3D V5 V6 0.2mm 0.3mm 0.4mm 0.5mm 0.6mm 0.8mm 1.0mm for 1.75mm Filament 3D Printer

Having clogging issues with the 0.2mm, but thats just part of the 0.2mm experience and not necessarily an issue with this nozzle. Make sure you keep your temps high and your print speeds low. Produced some great quality prints with a little trial and error.

So far so good.

I tried one of these on my Prussia MKS but did not get a smooth bead. Put the old nozzle back after cleaning with acetone and the extrusion was smooth. I don’t have the equipment to tell if the 4mm bore is smooth enough In this inexpensive nozzles but seems to work fine for others.

Received the product. Very quick shipping. Not fully tested, but thus far works OK.

One of the nozzles in the pack was very clearly already used.

The best thing about them is that they are cheap! For a few paltry dollars, you can get get an entire set, nay, several sets, of nozzles for your E3D V6 compatible hotend. I have tried the 0.8mm nozzle thus far and it did require recallibration of my Prusa MK3S but turned out a decent print. I was curious as to how accurate the nozzle diameters were so I put them under a stereo microscope and took some pictures. I then used the 0.8mm nozzle diameter as reference to measure the rest of them. All were spot on except the 0.2mm one which varied in diameter between 0.16 and 0.20mm, but given that this is almost surely going to be unused by me, Im not sure I care. The insides dont have burrs but they are not super smooth either: you can see the grinding pattern in the attached picture. Worth a buy? Yes, especially given that a single 0.4mm E3D nozzle sells for $25 on this site (dont know why!).

muy bien embalado, buena calidad

They work fine. No complaints

They fit my E3D V6 clone heat block. Packaging could definitely be better, i.e., packed separately by size. I grabbed a .6 when aiming for a .4 and it took a few mm of filament and confusion to realize that I had a mismatch. I have since repackaged in small bags that I had saved. But, they work and seem to work appropriately. A close examination revealed good clean orifices, edges, etc., and performance has met expectations.

Works great. Have lots spare, and avoid the hassle of cleaning a blocked nozzle
