Official Creality 3D Hotend Silicone Sock Set of Three and Creality Sticker for Ender 3 CR-10 CR-10S

I kept using the hotend with original insulation. It looked nasty. It came off so it was the time. This thing fits nicely. I dont know if this helps hold temperature but it looks nice.

It seems like a quality product, but the shape does not fit the stock ender 3 block

Fits perfectly once you re ove the tape and clean the filament blobs all under that nasty tape. Not sure why I need 3 of them but it’s nice to have spares. Slips right on and you can take it off to clean. Holds heat well and insulates much better than the factory tape

work exactly like it described.

I got these to replace the insulation that came pre-installed on the heater block. I put it on and it wouldnt stay because it was totally over-sized. Dont buy unless the size is fixed.

Fits great. Nice bumper sticker.

Not designed for any of the advertised printers, and didnt include the sticker.

These parts came fast and fit like a glove.

Perfect fit for my ender 3 machines

This sock does not fit properly. Please see the picture. This sock does not fit the stock CR10 heater block very well. It leaves an air gap, greatly reducing the insulating ability of the sock. 2 stars because they fit on the block, but dont actually fit like they should. I will not be using these. I would not buy these again.
