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

I think that was my fault though.

Nice replacement for that paper cloth nozzle wrap around my CR10s model printer. Keeps my hot end hot and havent seen any temperature drops.

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 needed to replace the stock insulation of the my Creality Ender 3 Pro because the material became brittle and began cracking by continuous use. I only had to remove the parts that were still adhered to the extruder hot end and put the new sock, less than 1 minute of work. I feel very happy with the result. I need to wait longer to jump to conclusion but it appears to mitigate some heat creep that was causing issues during printing.

Works ok, but wont stay on heat block unless tapped on with kapton tape strips

Does what it is to do

Fits well in Tevo tornado

Silicone socks are the best thing since sliced bread! These will insulate the hotend to keep temps stable as well as keeping it clean! This is a great price for 3 of these.

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!

Awesome. But be sure to clean the factory insulation off the hot end before putting one of these on.
