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

Perfect fit for my Ender 3

The socks do help a lot with keeping the hotend from getting all gunked up and as far as insulating for temperatures, not sure if it really helps too much. Performance I have found with the end piece will not really be affected =)

Fits perfect on a Creality cr10 v3

Works great

I ordered these for my Ender5 after the stock one got brittle and broke. I put one on then heated the hotend to 245 to print PETG. At around 230 it started to smell awful and smoke started to come off the sock. I let it sit for awhile to see if the smell would go away, but it didnt. Would not recommend.

Thanks! Would buy again.

Was initially skeptical about price and quality but it fits the Ender 3 hotend great without any issues. Color is a bit strange but functional nonetheless!

Finally! It was harder than it should be to find a correct fitting silicone sock for my cr10 v3 and cr10s but these are the ones. Absolutely perfect fit.

Fit perfectly good replacement.

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