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)

I bought these for my stock Creality CR-10 v3. They dont fit 100%, some machining is required to get a perfect fit. As they are the block has to be really close to the heat sink and the nozzle looks like it is sticking out more than it needs to. All in all, it works fine but is not a perfect fit.

does not fit the heater well, lots of slop. will need heat sink grease. didnt come with ANY screws.

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.

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.

this heats up faster than my v2 which use to out-pace my 3 pro will be switching my v2 to one of the extras soon to compare speed buy this product its good

Im using this on my longer lk5 its working

Its exactly like the original part, easy to replace. I wish i could buy 1 but since its not expensive then no a real issue, a bit of a waste tho

Does not come with screws, threaded piece is too long, and there is no nylon ptfe tube on the inside.

good parts.

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.
