CCTREE 3D Printer Hotend Silicone Sock Heater Block Silicone Cover for Creality Ender Series, CR Series, Anet A8, MK7/8/9 Hotend, Brown,3 Pcs

They work perfect on my Ender-3 v2 printer.

very nice

I am not sure if I got a defective set but it did not fit very well (had to trim it a bit to put it on my printer). Also, did not even last a month :(

I think these are a good idea and helps work several issue, these for average but I installed the without removing anything so it wasnt as easy going as it could have been.

It is to big for the ender 3 s1 plus. It falls off.

Fits perfectly in my ender 3 pro. Would recommend this product to any one how has ender 3 it is easy to install, works great, and keeps the heat were it need to be.

The Mk9 Silicone Sock seems to be a bit small for my hot end. While it does hold on and doesnt interfere with my printing, the four corners droop down because the lip on the sock wont catch the top of the hot end.

this was a dumb purchase on my part, they really disnt do much of anything any better than stock

Its never stated in the description, so I didnt realize that you have to remove all of the insulation that Creality wraps around their heater blocks in order for these socks to fit as intended. Im not sure Ill be doing that to my CR10 and Ender-3, so Ill keep this set of CCTREE socks I just bought in the drawer until I decide whether or not its worth it. A custom sock covers all but the very tip of the nozzle so curling filament wont stick and melt to it. Thats the main benefit for me - that and the minor heat stability improvement the covering provides. Considering the Creality hot-end is already insulated and considering that this sock leaves the nozzle completely uncovered, there really doesnt appear to be much benefit after all.

If I could give these zero stars I would. These are absolutely worthless, don’t even come close to fitting. The only saving grace for me as I throw these in the trash is I didn’t spend more money on this vendors product. Unless you want to cut and somehow glue these pieces of junk in place don’t waste your money. Anything branded cctree in the future will be avoided by me
