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 help keep the temperature stable so I’m happy.

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.

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.

This doesnt fit MK8 CR10s, even the item say MK9. Dont buy if you have MK8 nozzle block if you have the upgraded module it come with MK8 nozzle! Had to return it!

Had initially thought it didnt fit my CR-10 V2 but realized that there was just a bunch of melted PLA around the heater than needed to be removed.

Allows for steady nozzle temperatures.

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

Perfect fit cr10s

Good to have a few of these around for when the original wears out

Perfect
