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

These are a perfect fit, well made and attractively colored.

These do not fit an Ender 3/3 pro properly. Plain and simple doesn’t fit.

They work great on ender 3. And cr10s at lease it works for my 2 printers

Great replacement to the stock sock, even fits better! Will buy again.

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.

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.

Its perfect fit I like the color blue. It matches my machine.

I use these on my Micro Swiss hot end and they fit perfectly!

Lowered the print temperature of my printer to the recommended temps of the filaments purchased!

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