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 legit silicone socks for MK9 hot ends. I use this for my CR-10 printer with an upgraded Swiss all metal hot end. The sock this one replaced lasted me about 3 years. These are definitely wear items. They get hard and burnt over time.

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

These work okay. I dont think they work as well as the original tape and insulation. However, they were much easier to install. I am using on a Monoprice Mini (I think it is the first model). They dont fit exactly right but arr good enough. They did smoke a bit (@250c). That only happened for the few minutes though.

I love these. Took a second to put on and is a great alternative to stock.

So I got this for my printers after a different set didnt fit. These were perfect. I took 2 and cut them with an xacto knife and they fit great. The picture with the black shape is the cut away and hole I made to have it fit my monoprice mini. The other 2 images of the one with an entire side cut off was what I did to get it to fit my prusa MK2. They hold in place great no issues so far.

Theyd work better if they fit a little snugger. But the color is a nice change from basic black

Works great

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

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

Exact fit
