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)

Very good replacement for my wore out socks. They fit a lot more snug then my originals and keep the nozzle up to tempature.

Really happy that I switched over to these.

As described

These work great

dont say it works for an ender 3 pro when it doesnt

I had to buy new silicone socks as the one that was on my 3D printer snapped for some reason. These came quickly and it just fit on and I was back to printing within minutes. Well worth buying and I am buying more for my other printers.

Works much better than the fiber and tape. I use this on a mk8 hotend.

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

I have been really happy with my purchase. I had previously bought another brand and while it covered the hot end they never really seemed to fit snuggly or smoothly. This is by far the best fit that I have found, and I have no need to look any further. I did have a failed print over the weekend and a monster blob of filament occurred, like most of us have experienced, however, clean up was super clean and simple, and easily detached from the silicone. and it has a nice little Cr logo on the front.

This replacement did the trick. Worked perfectly. Was easy to install, just slipped it on. Somehow my original cover tore and would not stay on.
