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

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.

IF you own a 3D printer you will have failed prints from time to time and you will always have some small amount of plastic want to stick to your hot end. This can eventually foul the hot end making repairs difficult to impossible including changing nozzles. This eliminates that concern. Went more than a year without one and eventually had to replace my hot end. Since Ive started using these the hotend is never messy. It is consumable so getting multiple units is important. Order new ones when you install your last one. Shame that the mini didnt ship with one. CR-30 did but is Mandatory on that printer. Will never do without one again.

Fits perfectly on the Prusa Mini hotend without blocking the cooling fan airflow. Ive used the orange with no issues and decided to try the black. I havent had any issues with the black silicon either. I would definitely recommend this sock for the Prusa Mini or Mini+

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).

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

These are the best fitting for the Prusa mini, and do an amazing job. Totally worth it

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.

No problems at all.

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.
