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

Quality seems to be good.

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.

I really didnt know how much I needed these until I got them. Now I am not sure how I was able to get along without them. The size variety makes it easy to clean various size nozzles. I mostly use .4 mm nozzles and I do not hav any issues with these fitting. It can be a little difficult at times to insert them into the nozzle because of how small it is, but over time you development the ability the do it easily. The ends are sharp and pointy so be careful. I like the tweezers. These are a nice bonus. I have actually spent more on a single pair of these then I spent on this whole kit. I use these for much more than just cleaning the nozzle. The quality of this set is well worth the price.

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!

Highly recommended for anything with the 3D printer

Good item for Ender 3 maintenance.

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

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.

They fit the nozzle!!!
