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

Installed with no issues, running for 2 days now and Im very pleased (installed on Ender 3 Printer)

A must have for 3d pritners!

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

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

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

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

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.

Great deal for 3

I think that was my fault though.

Fits well in Tevo tornado
