Official Creality Ender 3 s1 Heater Silicone Sock, Heater Block Silicone Cover for Creality Ender 3 S1/Ender3 S1 Pro/CR10 Smart Pro/Sermoon V1/Sermoon V1 Pro 3D Printer (Pack of 5)

It fits perfectly on Ender 3 Pro, and covers really good the hot end maintaining constant temperature.

Product arrived when it was supposed to. Only took seconds to install as was a perfect fit on the stock hotend on my Ender 3.

Fits over standard heater block for ender 3 (i have a microswiss on but its the same size) Stayed on... easy to install... easy to remove... does the job

These work great

I was a bit skeptical at first, other customer photos looked different than the listing, and some review claimed there was a part that needed to be cutout. NOT THE CASE! While these looked slightly different than the listing photo, they have a smaller nozzle hole, they do fit more tightly around the nozzle and cover a bigger part of it, with just the tip poking out, BUT... I am pretty sure that is on purpose, Creality must have updated their design. These do have the Cr embossed on the side, and are made of nice GOOD silicon material. Also if still in doubt, I can confirm that i just received and Ender 3 Pro (July 2020) ordered from Creality and it came pre installed with a sock that is identical to these ones instead of the traditional wrap. For any MK8 Hot end, I can confirm these are the real deal!

Fits great and works better then the cheap stock material the cr10s printer comes with

Easy to replace on the ender 3

ive only had to use one but just as good as the stock one that come on my ender3v2

The actual silicone socks that were delivered don’t match what was shown in the pictures. They don’t have the extra hole for the grub screw.

Fit my Ender 3 no problem. Doesnt actually cover the side with the thermistor or heater cartridge, but doesnt seem to matter.
