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

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

Fit perfect an does what its supposed to

These silicone socks are great. I have one installed on my CR-10s. I let my stock insulation get gross over time and finally switched to one of these socks. If I could do it again I would have put one of these on when the printer was new. The install is dead simple. It stays on and doesn’t move. Filament doesn’t stick to it and I have no temperature issues. I still have two extra. Guess that means I need two more printers!

Better than stock,my stock one melted (ender 3 pro)

Does not fit

I think that was my fault though.

You do not know what you are missing until you try them. Im impressed. My hot-end is clean, no smell and filament does not stick to it. By by kapton tape and insulation.

works like a charm

Work as advertised

Fits gold edition tevo tornado perfectly, no issues
