Aokin 3D Printer Hotend Silicone Sock Heater Block Silicone Cover for Creality Ender 3, Ender 3 Pro, Ender 5, Ender 5 Pro, CR-10/10S, Anet A8, MK7/8/9 Hotend, Blue, 3 Pcs

Ive tried a few different silicone socks that were either included with my Ender 3 or came from other sources (including the bright blue one included with the Micro-Swiss hot end) and these fit perfectly with both my heater block and the various nozzles Ive used. Compared to some of the other socks Ive gotten, this one seems to fit just right over the top of the heater block while others seem a touch too short.

Doesnt fit CR-10 as it says in the title

Perfect fit for my Ender 3

Good to have an extra one or two of these around, because if you have a bad clog, its going to get torn up when replacing the nozzle.

Doesnt fit the ender 3 and mine only came with 2 not 3

I feel like this sock is backwards to how I would want it to be. I tried finding a better match to my exact hotend but this was the best one. This is on a Monoprice Maker Ultimate 2 printer. My printer may be a littler weird, Im not sure. I would have expected the heater to pop out of the little slot instead of the giant open hole side. This was the only way the sock would fit for me though. I didnt like how loose the sock was so I added some wire ties to hold it on there. The way they are set up on there they will not touch anything but the silicone. I took a 8 gauge copper wire and unbraided it and then twisted 2 strands together to make the ties. Install for me was super easy but my printer can drop the hotend very fast. Just dont forget to remove the filament first or you will be like me and need to wait for a heat cycle first.

Doest not really fit Ender 3V2.

I had issues with my part cooler blowing on my hot end and caused my printer to work hard trying to keep it at the correct temperature. After installing the Silicone Heater block cover the temperature remained consistent and the printer did not struggle to maintain temps. Good quality with no issues.

They seem to work, I didn’t like the blue cap I had before, black is better.

I bought a CR10 from a friend. I noticed the silicone boot was missing, so I ordered this 3 pack. Quality of the boot seems ok, but it won’t stay on the nozzle block. If it does stay on, it hangs low enough where some stringy PETG will definitely pull it off. Going to return these and buy the originals from Creality.
