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

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.

I thought it was acupuncture needle, it is seemingly not

These tools will one day make working with your printer easier, sooner or later you will have a clog or a plastic mess on the nozzle that needs to be cleaned.

Good kit to have , worth the buy

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 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

Purchased this with the intent of cleaning my 3d printing nozzles. Theyre good and definitely the product that is described, but my only feedback is that its incredibly difficult to tell the sizes apart from one-another. They all look the same and its very difficult to distinguish using just the human eye.

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

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

The plastic tube for the needles was all broken.
