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

Fits perfectly in my ender 3 pro. Would recommend this product to any one how has ender 3 it is easy to install, works great, and keeps the heat were it need to be.

great for your 3d printer, makes cleaning easy in the case of a gunk up.

Great deal for 3

This doesnt fit MK8 CR10s, even the item say MK9. Dont buy if you have MK8 nozzle block if you have the upgraded module it come with MK8 nozzle! Had to return it!

Fits well in Tevo tornado

they fit perfectly and I now have some spares.

I am not sure if I got a defective set but it did not fit very well (had to trim it a bit to put it on my printer). Also, did not even last a month :(

Perfect for the Ender 3 3d printer!

I think that was my fault though.

Works ok not a perfect fit though
