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 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.

I thought it was acupuncture needle, it is seemingly not

I have a flashforge adventurer 3 and this helped unclog it

Product quality is decent. The value (price vs amount) is even better.

I ordered these to make a WDT tool for espresso and they worked as expected. This set is perfect for this. The needles exactly match the photo and measurements shown. The thickest two are 75mm long, and all the others are 70mm. This is a perfect length for a WDT tool. I used a wine cork and a 1/16 drill bit, and its a perfect fit: snug enough to hold them in place, but with enough play that you can adjust them with needle nose pliers so they all extend the same length. I used 5 for mine, but 3-4 work too. My only (tiny) complaint is that there is nothing to identify which diameter needle is which. It was easy to eyeball them and find the two 0.15mm and 0.25mm, and obviously the two 0.50mm ones stand out in three ways: theyre 5mm longer than the rest, are clearly the thickest, and the color of the handle is more coppery than the rest. But I was hoping to know whether 0.40mm or 0.35mm made the best WDT tool, and was going to start with the 0.40mm needles that Decent Espresso recommends. Lacking a micrometer or other tool, I couldnt tell the difference between them. No big deal, I guess. I randomly chose five needles from the ten 0.35mm and 0.40mm ones for insertion into the cork, and I doubt its going to matter which ones I chose. I only wish they used a different color wrap for each size, with a legend to let you know which was which. Nonetheless, Im not deducting any stars; this was a great value and if you want to make your own WDT tool, this is all you need, as long as youre a wine drinker. If not, ask a friend who is to save some corks for you. I may eventually use a champagne cork, which has the advantage of no internal corkscrew damage, and is also larger in diameter, but my normal wine cork is doing fine and the size actually may turn out to be better. I doubt this tool will underperform the Decent Espresso Puck Rake that costs $25-$29. I can match that price by buying this Printer Nozzle Cleaning Kit and a $20 bottle of wine. Save the cork, drill a few holes, and enjoy the wine. Or buy two $10 bottles and enjoy twice as much wine. Or buy five bottles of Four buck Chuck at TJs and youve got four spare corks and enough wine for a WDT Making Party! By the way, there are some DIY videos on making this tool yourself. You really dont need to watch; just get a 1/16 drill bit and drill some holes in a wine cork. As long as you have several wine corks, its hard to mess this up. Some suggest grinding the ends of the needles to reduce the risk of stabbing yourself, but seriously, thats not necessary. Just be careful when you use the WDT, and if you have multiple needles all adjusted to the exact same length, it will reduce the chances of any one needle penetrating the skin. If guess if it does, you might be giving yourself a tiny espresso-colored tattoo, but then you have a conversation starter! I highly recommend this kit for making an espresso WDT tool. You cant go wrong.

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 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.

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

Buy it if you need a homemade WDT tool!

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.
