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)

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

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

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.

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 :)

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

Placed on a Tevo Torando. Fit and works perfectly. The original was crossthreaded and leaked. This was a near exact replacement. Very pleased with the quality, fit and finish. Good value.

These might be better quality than the creality OEM units.

Got these for the Ender 3 Pro and they fit perfectly. Had to replace a setup today after some cheap PLA clogged up my whole extruder. These went together with no issues and I havent had any issues with leaking nozzle heads or anything.

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.

Ok quality but the silicone socks were not correct.
