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)

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

The depth for the screws are too shallow. So you need to hit the hardware store to get half an inch linger screws to make up for the fact they dont set 1/2 way into the block like they do on the stock cr10 v3 heater blocks. Just hit up ebay. Amazon doesnt have ONE seller that has the correct ones.

Fits perfectly

Perfect spare parts. I would buy these again

Its exactly like the original part, easy to replace. I wish i could buy 1 but since its not expensive then no a real issue, a bit of a waste tho

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.

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

Threading on the heater blocks is very loose. Both the nozzle and throat feel wiggly, whether I use the ones in the kit or ones I already had.

My old one got gunked up and because the part was so cheap I swapped it with this. Fit perfectly and was the exact same. I would highly advise this one cause of all the spare parts that come with it.

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.
