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.

this heat block would be perfect but i had huge problems with that little aluminium stem that threads in it leaked so much filiment that it ended up adhearing all the bolts and screws to my fin stack now i have to buy a whole new extruder head and heating element

Yeah I’m reading these good reviews and my mind is blown because I got mine and it’s not compatible with my ender 3 pro AT ALL. The hole for the thermistor is not wide enough or deep enough for it to even fit in the block. I tried to drill it through but the hole for the thermistor then intersected with the hole where the the nozzle and filament pathways are. So there’s no possible way to use the block with a thermistor while also being able to send filament through it. Well, I’m happy all these other customers got ones that worked, wonder why mine were different...

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

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

The parts fit perfect, great to have.

Mine didnt come with any of the the grub screws that hold the heater in place or the screws that hold the thermistor in place.

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.

for the price cannot complain at all super easy to install just remember some thermal paste for proper heat transfer to the heatsink so the Bowden tube doesnt overheat and clog.

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
