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)

these where used on my ender 3 and they fit perfect great upgrade from the stock.

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!

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.

These will work with the creality hotend, but they are not creality socks. you will have to cut a nipple off of it or it will cover almost the entire nozzle.

Exactly what I needed my block cover ripped while I was cleaning the nozzle for my CR-10 V2 these worked great for replacements. Easy install A little on the looser side but they work.

I just got the printer and noticed that it come with one already, so don’t buy these if you just bought a new printer. All and all though, i never needed to replace it so I just returned the ones that I bought separately.

Working great so far. Fits nice and snug, seems to have a good grip on the heater block / better design than some of the others I was seeing

The stock cover got stuck and melted in the extruder. This is a 1 to 1 perfect replacement.

I had no issues installing a new boot on my CR-10V3, It slid right on!

Keeps falling off. Ruined prints.
