Aokin 13 Pcs 3D Printer Nozzle Cleaning Kit - 10 Pcs 0.4mm Needles Cleaner and 2 Pcs Tweezers Cleaner, Stainless Steel Nozzle Cleaning Tool Kit

Mine arrives in a broken container, and on top of that they bend pretty easy like a little give is fine and expected but Ive had a few bend to a complete 90° angle just by trying to clean the nozel of my printer

I found that the acupuncture needle were not as thin, fine, as expected.

Not sure how it’ll actually work for cleaning a printer But I shoved the needles through a wine cork to make a cool little cheap WDT tool to distribute espresso.

Did not like that the pin sizes are not accurate.

Good item for Ender 3 maintenance.

These fine pins are tough enough to get the job done. I had a terrible jam of some sort and these got it clean.

The plastic tube for the needles was all broken.

The needles don’t fit my .4 nozzles

These are doing the job, so far. Would buy again and will!

I did not buy these needles for a 3D printer. Instead, I bought them to make a Weiss Distribution Technique tool, in order to prepare a puck of coffee for an espresso machine. For this purpose, they work quite well. I used a pair of needle-nose pliers to force the spring ends of the needles into a wine cork I had lying around. I used three needles to make my tool. That was it. Now, after I put my grounds into the portafilter, I put on a shot collar and use this tool to break up and clumps. It works nicely and I am getting more consistent shots.
