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)

Ok quality but the silicone socks were not correct.

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

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.

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

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

If you want to keep taking apart your hot end, this is the product for you. Filament melts and comes out of everywhere except the nozzle. Stay away

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.

I need to replace these parts in my Ender 3 as cheap Bowden tube materials have become permanently burned onto the inside of the threaded cylinder. I have tried acetone and other solvents to remove the residue, but enough burnt-on material remains to make me want to replace it. The threads on the new aluminum block for the nozzle and the threaded cylinder fit so loosely that melted filament is absolutely certain to seep into the spaces in the threads. This is a poorly toleranced product and I will be returning it.

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 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.
