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 saw a number of these types of products for sale and, unfortunately, I chose the wrong listing or seller. As you can see from the photos one of the tweezers arrived unusable. The tips do not align, nor are they able to sit flush - it is a 2 fold problem. I give 2 stars because the other items were useable. I didnt want to return the whole thing because its so cheap and some of the items are still useful, but they should not sell stuff of this quality. I would probably be totally satisfied with the product if it werent for one of the two tweezers being junk. *** updated to 5 stars because the seller reached out to me on their own behalf and made it right. This really left a pleasant feeling because so many companies today forget about you after the sale. Kudos to them for standing behind their product and rectifying a mistake.

I bought this to use for making a WDT tool to rake my coffee grounds for maki g espresso. It works perfectly fine for my purpose

Quality seems to be good.

Great size for WDT

The description says they are nozzle cleaners for 0.4 mm nozzles. However, the provided needles do not come anywhere close to fitting a 0.4 mm nozzles. They appear to be for a 0.6 or maybe even a 0.8 mm nozzle. Had to return them.

The tweezers have proven invaluable and I use them regularly. They are fairly easy to bend, but theyre really pointy/thin so I wouldnt really expect otherwise. The nozzle cleaners are the correct form/shape, but they are way too short to be of much use. They should be 50% longer.

I bought these to push into an old champagne cork as use as a WDT tool for evening out my espresso grounds in the portafilter. Making it was a breeze and itll do much better than the toothpicks Ive been using!

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.

These tools will one day make working with your printer easier, sooner or later you will have a clog or a plastic mess on the nozzle that needs to be cleaned.

With those now I can clean my nozzle so easy, without troubles.
