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)

No complaints from my son and he prints every day!!!

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.

Perfect fit to replace the original sock. Having a spare or two is always a good idea.

Overall these seem to work well at insulating my 3D printer hotend. I was having issues getting my hotend to heat up to the temperature I wanted, but one I installed one of these it was able to heat up to my desired temp and then a little more. Pros: - Solid quality - Good insulation - Easy to use Cons: - One that came in the pack was miss shapen a bit, nothing major that really affected function

Great silicone sock, but its of the new style that covers a lot of the nozzle, which can snag on a part of it slips down a touch. Ruined 3 prints.

Easy to replace on the ender 3

As described

The Product satisfied the criteria.

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.

the bearings needs some attention in this kit. i needed to add bike lube to get them smooth.
