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

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.

Purchased this with the intent of cleaning my 3d printing nozzles. Theyre good and definitely the product that is described, but my only feedback is that its incredibly difficult to tell the sizes apart from one-another. They all look the same and its very difficult to distinguish using just the human eye.

These are 0.45mm, not 0.4mm. They WILL NOT fit into a 0.4mm nozzle. I will be requesting a refund immediately, as these were falsely advertised.

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

Buy it if you need a homemade WDT tool!

Perfect for my 3d printer exactly what I was looking for

I kind of expected them to be as long as the ones that came with my machine, but unfortunately, they were a bit short.

Product quality is decent. The value (price vs amount) is even better.

The cleaners were not the size in the description. Instead of 100mm overall they are 70mm. To short for a WDT.

Highly recommended for anything with the 3D printer
