Kamo 5PCS 3D Printer 0.4mm Extruder Brass Nozzle Print Head for Ultimaker 3.0 mm ABS PLA Printer

These are awesome nozzles, i bought the olsson block for my ultimaker 2 because Nozzles are expensive and all the nozzles got clogged with there first prints. so i decided to give these a try and wow these are super amazing especially for the price will definitely be buying more in case of emergencies.Pros: Affordable, easy to install, reliable and easy to cleanCons: sticks out a bit definitely need to change your build plate height. need a different Socket to install and remove

We look to these nozzles as cheap disposable nozzles for a backup. The brass used to make these are very cheap. We've had the experience of one of these snapping inside our hot end when trying to replace the nozzle. No Fun! We had to disassemble the entire print head to disassemble the hot end and use an easzyout to take the snapped threaded part out. Talk about a nightmare! I wouldn't recommend these to anyone! Just save your money and buy the more expensive parts.Printer: ultimaker 2 extended +

Nozzles purchased for Ultimaker 2, which these supposedly fit. Body of these is at least 3 times bigger than factory nozzles. Not a huge issue, but the threaded shank is about 1 mm shorter than factory, so even with it screwed as far as it will go into the heater block, the nozzle leaks badly. Filament runs down the outside of the nozzle, burns, and ends up leaving brown streaks in the print. Totally unacceptable. Will try a few other things before I return them, but so far, I'm blazingly unimpressed.

These DO NOT install on a FlashForgeCreatorPro Dual Printer. I gave 3 stars because they really should have a list of printers they work on. However I'm sure they are fine on other printers.

I purchased these extruder nozzles for my Ultimaker 2, and they fit well! The more experimental filament I use on my machine, the more wear & tear I get on my brass nozzles. They need to be replaced often when the jams become too frequent or prints start to fail. This 5x pack is great to buy for the periodical nozzle exchange. It heats up well and evenly and the wear is no different from my standard brass nozzle. The only difference is the head itself is larger than the stock Ultimaker 2 head. It will require a larger socket wrench or pliers to unscrew. Other than that, it works fantastic.Kamo 5x 0.4mm Brass Extruder+ Innexpensive+ Brass+ Even heat distribution+ 5 pack- Larger head than normal

Fits Ultimaker 2 with the Olson block perfectly! Great buy!

WARNING!!!! Does not fit the Ultimaker 2 Olsson Block. Although it looks like it should fit to the naked eye, the spec are slightly off to not form a complete seal. Consequently you will have filament which will slowly leak to the backside of the block. Save yourself some trouble/time and don't buy these nozzles.

These heads are about twice as big as the originals and the 0.4mm hole needed cleaned out with a .4 drill bit.
