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)

Got these to have spares around, since I always end up needing them. And theyve been good to have around. Quality is on par with what you get on the stock hotend. Do note however that they dont come with any of the set screws. But the heatbreak works great with PLA, and heat block is a drop in replacement as well. Good price.

Threading on the heater blocks is very loose. Both the nozzle and throat feel wiggly, whether I use the ones in the kit or ones I already had.

These might be better quality than the creality OEM units.

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.

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.

Good product for my ender 3 pro. Had some issues hut the seller was quick to fix them.

really easy installation, just remove the wires pop it in and reattach. I always love installations you can do cold

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.

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