We go through about 60 nozzles every month on our print farm, but we also sell upwards of 500 or so per month as well. So obviously we buy a lot of nozzles. We get them from the same (chinese) dealer who has always been really good about getting us a few thousand at at time, and they do not mind our quality control checks or requirements. We asked them to source a higher cost nozzle for us as we were going to buy them in a large enough quantity we could get them for the same price as the lower quality nozzles. They sent us these to run through our QC checks:
Pretty sure they got the whole idea of 3D Printer nozzle wrong on these. LOL!
