V6 Silicone Socks (Pack of 3)

The sock is very useful from keeping crud building up on my hotblock (given I tighten my nozzle correctly). However, because of the 290c temps I print ABS at (seems to get better print quality with the brand I'm using) it ends up crumbling and welding to the hotblock after around 1 week.

Does the job as expected, but they don't last forever.
A telltale sign is when the rear of the sock starts to sag it needs replacing.
So buy a few, so you have spare at hand. Consider it regular maintanence to change your socks before they start to stink :)

It doesn’t last forever, but it fits well and stays in place. I’ve never had a print failure due to one of these over 1000s of accumulated print hours.

My only negative is that I would like to see it made out of a longer lasting material. I have started making my own using a high temp silicone and mine show no sign of degradation after months. But these are inexpensive and easy to replace.

The number of times we've had a print destroyed due to these socks is absurd.

Out of the 30 machines we have, on average 2 per week are in service because of these socks. They are just rubbish, and literally costing me thousands of dollars a month in down machine time.

Straight out of the box, they don't quite fit properly onto the extruder. They're quite loose, and once the extruder is heated up they tend to fall off.

Combine that with the fact that the silicon they are made of can't even handle the heat, and you're really disappointed. Seriously though, after 24 hours of use the socks will be visibly discolored, and become so brittle they just fall apart (Not exaggerating, they will literally fall to pieces). Really wouldn't recommend.

The fact that the community's solution to these is to literally design and manufacture our own molds, and remake them ourselves with high temp gasket maker just shows the failure for years in product development that E3D has had for it's community. Really disappointed.

Does it's job very well, but due to loose fit, they are not optimal for production use, they last us less than a week (almost 24/7 use) before being cooked up and fall, normally resulting in a damaged print.
