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)

Fit my ender 5 pro with a gulfcoast robotic all metal hotend perfectly. The stock one would not stop leaking no matter what I tried and these new blocks finally fixed that. Quality and finish seem to be better than original so far. Would definitely recommend.

I broke the SS throat that came with my printer. The original may have been aluminum, it completely snapped off. But these fit perfectly. Its a great deal to have this many spare parts at such a great price. You saved my day.

These heater blocks do not fit the CR-10 V3. The screw holes do not line up.

I went to use these and noticed that the heater cartridge fit into one block but not another. Same went for the throat where the bowden tube fit through one but not the other. So one set was wasted.

Very happy with this vendor (on-time) and product. Copper heatsink and filament tubes machining is accurate . Have been purchasing complete heater assemblies. This replacement kit lets you trade out the hot parts of the head without having to re-snake and re-attach the leads. Smart up grade. Be sure to have a hand held Propane torch to loosen the screws from your existing assembly. Again a smart purchase if you have the tools!

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 :)

Yeah I’m reading these good reviews and my mind is blown because I got mine and it’s not compatible with my ender 3 pro AT ALL. The hole for the thermistor is not wide enough or deep enough for it to even fit in the block. I tried to drill it through but the hole for the thermistor then intersected with the hole where the the nozzle and filament pathways are. So there’s no possible way to use the block with a thermistor while also being able to send filament through it. Well, I’m happy all these other customers got ones that worked, wonder why mine were different...

Great price. Nice packaging. Great quality. You get exactly what you pay for.

Becareful it doesnt come with the tension screw for heat element and lock screw for thermistor

The parts fit perfect, great to have.
