Ender 3D Printer Parts Silicone Socks/Aluminum Heater Block/Stainless Steel Throat for MK7 MK8 Extruder Kits Ender 3/Ender 3 Pro/Creality CR-10 /CR10S /S4 /S5 (3 Packs)

Mine didnt come with any of the the grub screws that hold the heater in place or the screws that hold the thermistor in place.

Got these to have spares around, since I always end up needing them. And theyve been good to have around. Quality is on par with what you get on the stock hotend. Do note however that they dont come with any of the set screws. But the heatbreak works great with PLA, and heat block is a drop in replacement as well. Good price.

So far only used one block after stripping out my original one on my Ender 3 Pro. There was absolutely no issue with alignment for me and everything has been working the months since with a lot of printing. However I am knocking off a star for not having any extra screws. I had almost lost my original screw twice during the swap and not having an extra wound of been very inconvenient and aggravating. If they start including the screws this would be a near perfect product in my opinion. Update: Even after about a hundred additional hours of printing and months later they are still holding up great. Not that its surprising as they are just chunks of aluminum after all. But there is no difference I can tell even with thousands of hours of printing between these and the ones I replaced. Flow is good, swapping nozzles is good, temps are good. It just works :)

For the price I paid (under $14.00) this is an excellent deal. Parts appear to be equal to the original Ender 3. Printing at 205C the silicone hood doesnt smoke or smell. I do wish the set included grub screws, but I still have to give it 5 stars for the value.

These might be better quality than the creality OEM units.

This product is not made correctly. They drilled the recesses for the mounting screws on the wrong side of the block so the thermistor hole is on the wrong side of the block.

So far so good. Fit my Ender 3v2 perfectly after I damaged my OEM one they came with the printer. Great value and installed in under 5 minutes. Seems to come temp at a quicker rate as well.

Seems OK. Not sure why they anodized, would be cheaper and better if they included the set screw and thermo screw

The depth for the screws are too shallow. So you need to hit the hardware store to get half an inch linger screws to make up for the fact they dont set 1/2 way into the block like they do on the stock cr10 v3 heater blocks. Just hit up ebay. Amazon doesnt have ONE seller that has the correct ones.

Didn’t fit what it said it would
