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 work perfectly to replace the heater block on the CR-10s. However, they do not contain the screws for the heater cartridge or the thermistor. It would be nice to have those included as you may not have the ones from your old one (like me).

Ok quality but the silicone socks were not correct.

Awesome replacement quick install would buy again

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.

These do fit correctly and function good but they do not give you the set screw for the heater cartridge or the screw for the thermosistor or even a new set to hold down the block. so if either of these screws are messed up on yours dont order these you will not recieve any screws at all.

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

Replacement parts for my ender 3 pro, works with no issues

The silicone socks that came with my pack partially cover the nozzle. I really like this and consider it an upgrade, it prevents PETG strings clinging to the nozzle and has worked well so far. Just FYI, doesnt look like the product shots. Otherwise, I cant believe how shredded the threads were in my original heatblock, this replacement is well constructed and nozzle mounted firmly.

Got me up and running again, but the threads are crap and lose. The socks dont fit so well. I guess I will use them for making nozzle cleaners or something.

Not sure what other negative reviewers are getting, but the ones I received are spot on. These are an exact match to the original, though I do like the gold anodizing on the heater block better than the stock bare aluminum. Im in the middle of a 2 day print with no issues.
