Changing out my Hemera's nozzle, so bought a few of these as my stock one was looking a bit rough… Perfect fit!

Came reasonably quick, were affordable and actually fit which is more than I can say for the ones I ordered from Amazon.

I placed an order for other things but decided to replace my old e3d sock because I know it fits and keeps things clean down there. It is on a stock Prusa 2.5s hot end btw.

Works just as advertised. My Prusa i3 MK3s heats up much faster now, it also maintains a more consistent temperature. Easy to install. Shipping to the US was fast and easy. I would not hesitate to shop with Spool3D again.

It definitely works but this sock seems to be a little off in terms of quality. For one it smelled a bit to the point i thought i was printing with abs by accident (i dont even use abs) though that went away after a while. Functionally its great and fits the nozzle well.

works as advertised and keeps the hot end free of debris

Fit my Prusa perfectly. Works well and affordable.

I'd give if five stars but they do wear out after quite a few hours. They are best fitted by using some fine wire around the perimeter that keeps them from working off if they get clumped up and you are trying to remove the clump which must be done hot or you will destroy the sleeve.

The product is a good idea but in my experiences they don't fit well and I've had them fall off and foul up a print. Accidents never happen when you are watching and we all know you just can't be there all the time.

Good sock, fits well.
