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

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

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.

Did not like that the pin sizes are not accurate.

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

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

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

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 use this to distribute ground coffee in my espresso maker. Good value, works perfectly for my application. Have recommended to others Have no idea if this will clean printer nozzles

Quality seems to be good.

Buy it if you need a homemade WDT tool!
