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)

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

i needed them to work and they did

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).

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.

Ok quality but the silicone socks were not correct.

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 :)

So far so good. Fit my Ender 3v2 perfectly after I damaged my OEM one they came with the printer. Great value and installed in under 5 minutes. Seems to come temp at a quicker rate as well.

Perfect spare parts. I would buy these again

Worked great on creality ender3 pro! Would buy again if I needed to.
