3D Printer Hotend Silicone Sock, 6 PCS Heater Block Silicone Cover for Creality Ender 3/3 Pro/3 V2, Ender 5/5 Plus/ 5 Pro, CR 10 Series, MK7/ 8/9 3D Printer Hotend

My stock cover had torn and was looking for one that fit. This one fits just fine, there is one thing I was to point out though. You will need to remove it if you want to clean the nozzle as it covers most of the nozzle only leaving the tip visible. Not really a con for me, but I did want to point that out.

Just as good as original. Perfect fit. Just buy this one.

Silicone sock helps keep the temperature of your heat block steady and keeps things from sticking on to your heat block. Perfect to keep those temperatures constant for better printing. Also, these last longer than the Kapton tape and fiber pad that most printer come with. People do not put the tape and fiber, back on causing inconsistent heating in the print head. This can lead to imperfections in your prints. Order a pack with extras for your other ender printers these come in very handy.

These worked great on a stock Ender 3 V2 but... upgrading my hotend to the Creality Sprite(pro) these will no longer work as the nozzle was moved to the other side of the sock. So, I'm back to the store to buy some Ender 3 S1/Sprite silicone socks. :)

I've run my Ender 3 pro many years. The heat sock started crumbling, so time to replace. These parts give me the replacement and spares. It fits like a sock. Sorry for wording but described it well.Printer returned to ready to use status quickly.

Fit my SV06 same as the original. In fact I think it's the exact same one it came with. And now I have spares. Great buy.

Sometimes, over the course of 3d printing, you realize that your hotend sock has started to wear, and you could probably use another one.Sometimes, over the course of 3d printing, you don't tighten the hotend enough, and have filament leaks into your hotend sock causing it to become irreparably bonded to that filament.No judgement here - if you're looking at these hotend sock replacements you could probably use a hotend sock replacement, for whatever reason. Good news, these are they. Well, as long as you have an Ender 3, or whatever other printer this says it's compatible with.There's not really a way to screw up the manufacture of these - they are what they are, and it's nice to get a six pack so that if you do ever find yourself in need again you have a few sitting around.

They work well for keeping plastic from sticking to hotend.

They simply work.

As described.
