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

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

Used this to make a WDT tool for espresso, worked like a charm

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.

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

The plastic tube for the needles was all broken.

This is useful for some people, but I have never needed it.s

Needles to a decent job of helping to unclog nozzles. Dont expect to completely clean it out, but you can get the flow going again. They are easily bent. So, take care when using them. The brush is good, the tweezers are ok. Not as strong of a grip as I would like. I was hoping to also review the needles use in acupuncture, but my wife wouldnt let me try them out on her. I dont understand, I had a copy of an ancient Chinese acupuncture chart and everything. She is no fun, but I do lover her. The kids never let me try any of my ideas. So, I didnt even ask.

Good kit to have , worth the buy

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 have a flashforge adventurer 3 and this helped unclog it
