Creality 3D Printer Parts Upgrade Heater Block Silicone Cover and Brass Nozzle Tips for MK7/MK8/MK9 Extruder Hotend Sock Heat Insulation for CR-10,10S,S4,S5 Anet A8 Ender 3 Pro V2

Perfect fit for stock Ender3 V2.

It does a fantastic job keeping things cool. I’m able to run PLA parts coolers almost touching the extruder.

Unlike some of the other Silicone Covers available, these were just like the originals. They fit and work just as good as the original cover that come with the printer.

I used to make little rubber parts. These are good quality.

i ordered this because i did not want rubber around my nozzle. if i wanted a version of the silicone sock that had rubber around the nozzle i would have ordered them, because unlike this listing, they had double the quantity. not happy. not worth going through the process of getting a refund and getting the same item from the same seller under a different name.

Perfect fit, exact replacement for the factory part on my Ender 3 Pro.

Fits perfectly but I had to adjust my temp levels because this version sits lower and covers most of the nozzle and since my settings had already been adjusted for heat creep, it’s too low of a temp now. It’s an easy fix and I adjusted the temp a few degrees hotter so keep this in mind if you have your settings set to avoid any heat creep. Otherwise it’s a perfect fit for an Ender 3 Pro.

Other brand smelled horrible when heated and smoked. These are fine.

Not much to say, standard heat sock. Seem to hold up pretty well to wear.

Cheap enough to change when switching my Ender over from long PETg print back to PLA. They work great.
