Updated High Temperature CR-10 Plated Copper Heater Block for MK8 Extruder Creality All Metal Hotend Ender3 V2 Ender 3 pro Ender 5 Pro Plus CR10 S4 S5 3D Printer (Copper)

For a very similar price to stock you can pick this up instead. Sizing is prefect and installs with no issues. Better heat stability then OEM. Great upgrade.

Great replacement. Perfect fitment

I built a custom CR10 that runs Klipper. This was the first setup I used on it, I've since gone to a ceramic heater since it heats up better. This worked as it should and if I still used that setup I'd buy one again if needed.

Easy to install and works exactly as expected.

It's mostly good. If any one is wondering if weighs about 25grams. It has a thermistor and thermocouple hole. My big issue here though, is the placement of the thermistor hole.... It's right next to the heater element. This is not good for accurate temp control. I used a 5/64 drill bit and made a new hole. I failed the first time, turns out the thread walls are thinner than I thought. The threading and everything else is nice about this unit though. For comparison I included a creality, and micro swiss heatblock.

Heavy and holds the heat much better than aluminum.

These heat blocks are not a direct replacement for the Ender 3 V2 as noted in the title and description.The first one did not fit due to mounting screw holes alignment off by 0.5mm. I contacted Amazon, they sent a replacement at no charge. The replacement has the same issue. In my opinion these heat blocks are definitely NOT a direct replacement as advertised!!!

Worked perfect as a replacement for my Micro Swiss extruder.
