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)

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.

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.

I broke the SS throat that came with my printer. The original may have been aluminum, it completely snapped off. But these fit perfectly. Its a great deal to have this many spare parts at such a great price. You saved my day.

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.

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.

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

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.

For the price I paid (under $14.00) this is an excellent deal. Parts appear to be equal to the original Ender 3. Printing at 205C the silicone hood doesnt smoke or smell. I do wish the set included grub screws, but I still have to give it 5 stars for the value.

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

does not fit the heater well, lots of slop. will need heat sink grease. didnt come with ANY screws.
