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

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

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!).

Trying to find nozzles to work with the JGAurora A5S printer without having to wait for them to arrive from China. Purchase these. Arrived in 3 days. They fit perfectly. No issues so far.

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

They do just what theyre supposed to.
