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

The nozzles appear to be of decent quality, no visible machining defects, and the interior bores appear smooth on inspection. I dont have a microscope to examine closely, but I had no issue pushing an appropriate feeler through the nozzle, and felt no binding or restrictions. I did not read closely the description, and honestly have no use for the larger 1.0mm nozzles, and will probably never use the 0.8mm nozzles due to limitations of my machine, but the rest are fine.

Worth the money

Working great immediately installed after delivery! Good deal.

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.

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.
