Aokin 3D Printer Hotend Silicone Sock Heater Block Silicone Cover for Creality Ender 3, Ender 3 Pro, Ender 5, Ender 5 Pro, CR-10/10S, Anet A8, MK7/8/9 Hotend, Blue, 3 Pcs

Its perfect fit I like the color blue. It matches my machine.

Does not fit Ender3 inner diameter is not 20mm

Finally! It was harder than it should be to find a correct fitting silicone sock for my cr10 v3 and cr10s but these are the ones. Absolutely perfect fit.

Fits perfectly on my replicator 2 and hasnt fatigued a bit in the last 100 plus hours of printing.

Thanks! Would buy again.

I had issues with my part cooler blowing on my hot end and caused my printer to work hard trying to keep it at the correct temperature. After installing the Silicone Heater block cover the temperature remained consistent and the printer did not struggle to maintain temps. Good quality with no issues.

These are too soft to stay on properly. When they get warm, they become soft and want to slide off. There really isnt much that keeps them attached in the first place.

Works perfectly to cover my ender 3’s hot end! I bought another pack as well so I’ll have extras for a good long while.

Doest not really fit Ender 3V2.

These work okay. I dont think they work as well as the original tape and insulation. However, they were much easier to install. I am using on a Monoprice Mini (I think it is the first model). They dont fit exactly right but arr good enough. They did smoke a bit (@250c). That only happened for the few minutes though.
