POLISI3D Nano Coated Ender 3 Neo Bimetal Heatbreak Smooth Titanium Copper Throat All Metal Compatible with Creality Ender 3 V2 Neo/Max Neo, CR6 SE/Max/CR-5 PRO, CR10 Smart 3D Printer (Heatbreak)

Make sure to install while system is at temp. Works well so far and print quality has improved dramatically.

First it didn't fit my printer, that was listed in the compatible devices, second it got stuck half way and snapped so now I have to buy the whole hot end so I can use my printer again, what a joke!

Perfect fit for Ender3 V2 Neo. Good results with PLA, PETG and ABS. The included photos are of ABS parts for a Voron 0.2

I do not know why but this made printing worse. Everything I read suggested this will help with my specific problem but is actually made it worse. Furthermore, it snapped when I attempted to remove it. Essentially, it became a waste of money.

Product worked but not better than the orginal part.

Handles ABS High temp prints w/ no fan ON with my Ender 3 NEO. Great price and Amazon fast shipping.

Doesn't fit the Ender 3 Neo Heat Sink ! Will screw into the hot end just fine but just doesn't fit the Ender 3 stock metal heat sink.

The bimetal heatbreak isn’t properly milled to let filament through. The passage is too narrow and the filament binds up on the inside. This item had one job and failed.Sadly, took apart my hotend to install it and then recalibrated my printer before discovering this fact. Total waste of time. Don’t bother buying from them.
