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)

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

Fit my ender 5 pro with a gulfcoast robotic all metal hotend perfectly. The stock one would not stop leaking no matter what I tried and these new blocks finally fixed that. Quality and finish seem to be better than original so far. Would definitely recommend.

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.

i needed them to work and they did

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.

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

Does not work with Ender 3 evo. The tube metal part will not fit in the stock Ender 3 evo.

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

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

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 :)
