Works but thermistor wire is short
The block and heater work fine, but the thermistor wires were slightly shorter than my stock ones, making cable management tight. Functionality is unaffected though.

Perfect replacement for my Ender 3
My original heater block failed after a year of heavy use. This kit fit perfectly and was easy to install. The temperature stability is excellent now.

Great value kit
Buying this kit was cheaper than buying individual parts. Everything matched my CR-10 S1 without any modification. Highly recommend for upgrades.

Saved my printer
I stripped the threads on my old block and needed a quick fix. This arrived fast and got me printing again. Just be careful not to overtighten the screws.

Good quality, instructions could be better
The parts feel solid and well-made. Installation took a bit longer than expected because the included diagram was small, but once running, it works great.

Solid aluminum construction
You can tell this is made from good quality aluminum. Heat distribution seems very even, and I haven't had any clogs since installing it two weeks ago.
Q: Is the thermistor pre-installed in the block?
A: No, the thermistor is included separately in the package to prevent damage during shipping. You will need to insert it into the designated hole on the heater block and secure it with the provided screw.
Q: Does this come with a 24V heating cartridge?
A: Yes, the kit includes a heating cartridge that is compatible with both 12V and 24V systems, depending on your printer's motherboard configuration. Please verify your printer's voltage before installation.
Q: Is this compatible with the Ender 3 V3 KE?
A: This kit is designed for the standard MK8 extruder system found on Ender 3, Ender 3 Pro, Ender 3 V2, and CR-10 models. The Ender 3 V3 KE uses a different direct drive system, so this specific block may not fit without modification.
Q: Can I use this for printing ABS filament?
A: Absolutely. The heater block and cartridge can reach temperatures up to 250°C, which is sufficient for printing ABS, PLA, PETG, and TPU filaments safely.
Q: What size hex key do I need for installation?
A: You will typically need a 2.5mm or 3mm hex key to remove the old block and secure the new one, along with a small wrench for the nozzle itself. These are standard tools in most 3D printer maintenance kits.
