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

Fit perfectly good replacement.

Good to have an extra one or two of these around, because if you have a bad clog, its going to get torn up when replacing the nozzle.

These are great to have to prevent heat block buildup. They also make clean up easier whenever messes happen.

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.

Fits the standard Anet A8 heat block and nozzle.

Works great

Works great. Some other covers can fall off the heater block, but this one does not. I have used this for at least 40 hours so far.

I was looking for an inexpensive silicone hot end cover, and these fit the bill! They work great, dont feel like they are going to tear when being installed, and are a great value for the price.

Doest not really fit Ender 3V2.

I use these on my Micro Swiss hot end and they fit perfectly!
