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)

Good replacement. Not much to say, no leaks.

Im using this on my longer lk5 its working

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

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.

My only complaint is that the socks in the pics are the kind pulled back from the nozzle, but the ones delivered wrap around the nozzle. Still, the parts are well cut, fit like a glove, and I have no performance complaints in about 500 grams run through the first one thus far.

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

As there are 3 items in the lot, I will split it up into 3 parts: *Silicone Sock - Got the most use out of these things. They work in retaining heat in the hotend. My printer honestly doesnt need it, but it helps in keeping the hotend clean. *Heater Block - Looks like the stock block. Fits well with all-metal heatbreaks. Temperature probe and cartridge have no problems. There were screws for the heater cartridge. I did have some problems with the fact that there are no screws to hold in the temperature probe. Had to use spare screws, but it really should be included. *Heat-break - Didnt use these as I already have a pack of all-metal heatbreaks, but these are still useful as a backup. Overall a good pack of parts. Wish it came with those aformentioned temperature probe screws though.

My old one got gunked up and because the part was so cheap I swapped it with this. Fit perfectly and was the exact same. I would highly advise this one cause of all the spare parts that come with it.

Im doing enough printing that Ive found its wise to have spares. Ive only ever had to replace one after a bit of a mess coated one with goo.

Horrible!!! The hot ends I received didn’t have the thread for the screw to be threaded correctly. The pieces didn’t fit together right. Now I have one printer down with filament all over my hot end. What a mess!
