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 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.

My insulation on the hotend came off and needed a replacement. These were the perfect replacement. Very happy with this order.

Works fine. No issues.

Perfect

My only regret is that I hadnt installed this upgrade when I first set the printer up...fits perfectly with my Creality Ender 3, so happy with this purchase.

Work as advertised

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.

Works ok not a perfect fit though

Fits great on cr10 and definitely makes more stable temps

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.
