Prusa Mini/Mini+ Heat Block Black Silicone Sock X by levendig | dsgn [3-Pack] - Insulate & Protect Your 3D Printer Hot End Nozzle

For the first few hours of printing it gave off a stinky burned plastic smell, but then it went away. Looks clean, no issues so far.

I bought these directly from levendig rather than here on Amazon, so I know I have genuine parts. Unfortunately, running PETG at 250-260C, these socks last maybe 100hrs if youre lucky. Complete garbage.

Update: I can now strongly recommend this product. There is some weird offgassing smell the first couple times you use it. But after that it does exactly what it’s supposed to do to keep filament off the hot end and make your nozzle easy to keep clean. This fits the Prusa Mini+ hotend very well. But when I printed with it on for the first time using PETG at 240-230 degrees celsius there was a strong burning plastic odor/gas which filled the room. Not sure if this will subside over time as this is used, but it is unpleasant and probably not good to breath these fumes. So if it persists, I would have to downgrade my review and stop using this product.

My first impression is that the fit is exact. It took a while to continuously find the right spot to massage to get it to snap into final position. The upshot is an exact fit with no ugly slack for air to get to the block. Way better than the socks for my old MMSP. So far, so good.

I’ve been using these covers even before he put them on Amazon. They are perfect and fit all of my minis wonderfully!

Fit my Prusa Mini+ perfectly. Still testing improvements in print quality. Aesthetically, looks great and matches the Prusa Orange well (not a perfect color match, but remarkably close).

Fits perfectly on my Prusa Mini+. So far I have only used it with PLA at 185 degrees C and it works great. There was a very slight odor during the first few minutes of printing, but no other issues in dozens of hours of printing.

Dont seam to fall apart like last version.

Sock fit Prusa MINI perfectly. After lots of use it has not stretched or looks like it’s going to fall off. The temps are a bit more solid while printing. I would recommend since it’s a relatively small cost compared to the time you’d spend cleaning and replacing heater blocks.

Great price on this product that is exactly as described. Fits perfectly on my mini and only took seconds to install. I will order these next time I need some, but since they came with 3 and seems to be a really good quality, it will be a while before I need more.
