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

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.

Buy it if you need a homemade WDT tool!

These needles are too large for 0.4mm nozzle. I do like the 2 sets of precision tweezers though, I just wish the needles fit my nozzle....

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.

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

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

I mean they are what you see and they work as they should. Worth it in my opinion as I had some old filament stuck in the nozzle and the needles stuck in and I was able to push the new filament in as I pulled.

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

Great size for WDT

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!
