Genuine E3D V6 Socks Pro (Pack of 3) (V6-SOCK-PRO-3PACK)

Works well. Wish I ordered them earlier. Goes on with a little coaxing. One reviewer stated he only got 2. I thought the same thing at first, but the third one is behind the other 2, perpendicular and back to back with them. I'll get a pic posted later. I ordered 2 sets of 3, so I still have an unopened set.

The part that snugs right up against the nozzle usually doesn't last as long as the rest of the sock, but these are great and I wouldn't print without them. Even though you can.

Ordered these for a MK3S+ and due to the heater cartridge wiring the corner had to be removed. It also is a pain in the butt to get it past the part fan duct. The nozzle dimple is very tight fitting and if no forced into just the right position, fills with molten filament and gets pushed off of the hot end.

It seems to be a decent product but the area around the tip doesn't last very long. It is thinner than the surrounding areas and tears easier. Once it years I cut the center out.

Authentic E3D socks. Improves thermal stability for the hotend while also preventing buildup on the nozzle. Be warned however if you have a leak on the nozzle or heatbrake due to improper installation of the nozzle this will compound the resulting glob that will form.

As anyone who prints with PETG probably knows, PETG loves to end up stuck all over the hot end. Even if you don't have any mishaps, PETG still finds a way. Based on some research on the web, I found these and decided to give them a shot. The first caution is that they don't always stay up real well, even on an authentic E3D hot end. I just don't think there's quite enough lip around the top of the silicone, and it's super flexible, and you're applying it to a hot end working at temperatures up near 250C.The first sock I used, it kept tilting down, and was in danger of contacting the print. I pulled it off and replaced it prematurely after maybe 20 hours of printing. The second one I wrapped a tiny piece of bare electrical wire (other people will use a twist-tie and burn the plastic off it) and twisted the end. It held the sock up without any issue at all. It's kind of a pain to twist the wire, and you have to be careful of proximity to the thermister and heater wires. The third one I applied using a dab (just a tiny bit!) of high-temperature RTV on either end. This seems to be holding it in place perfectly, and was less work than twisting the wire tie. Both the wire tie and the RTV were tips I picked up reading a few forums from others who were concerned about the sock not staying on.Another issue I've had is that even when held in place, it still seems possible for the silicone sock, after it's degraded over a few tens of hours of printing, to start collecting some PETG right along the lower edge of the nozzle. I'm not sure if it's wiping a tiny bit off that's accumulating over time, but eventually it builds up enough to cause a problem. Replacing the sock solves the problem, at least for a while. These things are consumables, and like any consumables you should expect to replace them when their service life is exceeded.Deducted a few stars because the sock drooping could be a catastrophic problem, especially if it sagged sufficiently that it allowed extruded filament to build up between the sock and the nozzle. E3D does also sell a "non-pro" version that doesn't cover the whole nozzle like this one does. That might actually be a safer/better alternative, and I might give it a try after my current pack of socks wears out.

Was having a hell of a time with PETG sticking to everything...these socks are slick, problem gone!!

Very easy to install. Stops filament from sticking to print head should a part come loose or ...
