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 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.

Buy it if you need a homemade WDT tool!

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!

These fine pins are tough enough to get the job done. I had a terrible jam of some sort and these got it clean.

I found that the acupuncture needle were not as thin, fine, as expected.

The plastic tube for the needles was all broken.

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

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.

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.

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