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)

These are great. Installed my first one yesterday. Working like a charm. For those complaining about the silicon covers. Your the problem not the covers. They do fit. I noticed in your photos you have them on the wrong way. Definitely not a design flaw. User error.

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...

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.

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.

I was sick and tired of cleaning my old stock Creality Ender 5 hotend, and the last time I cleaned it I noticed the threads were amadaged, causing filament jamming issues. This kit arrived quickly and upon first install is working sufficiently. Im happy to have a silicone sock that covers more of the hotend; this exposes less of the nozzle so there is less of a chance of stray filament sticking and getting dragged around the print bed. The threads were clean and straight and the silicone socks were all clean. Very pleased and would recommend.

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.

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

Ok quality but the silicone socks were not correct.

Threading on the heater blocks is very loose. Both the nozzle and throat feel wiggly, whether I use the ones in the kit or ones I already had.

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!
