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)

The heat block has two holes for screws for attach the heatsink. The holes between the heatsink and the block are not align and there is no way to send a screw through both holes. Returning and looking elsewhere

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

Awesome replacement quick install would buy again

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).

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

Im using this on my longer lk5 its working

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.

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

I went to use these and noticed that the heater cartridge fit into one block but not another. Same went for the throat where the bowden tube fit through one but not the other. So one set was wasted.
