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

Dont seam to fall apart like last version.

No problems at all.

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.

I got this for my 3D printer and it’s working well so far, nice fit for my Prusa Mini 3D printer I wish it was a little bit thinner as it seems to come close to getting in the way of the nozzle

The Sock X is the one to get. A refined design and it goes on snug so not to interfere with cooling. Ive had no issues with this whatsoever, but its helped a lot with PETG (keeping it from getting stuck on the heater block/upper nozzle). Also Prusas documentation indicates their PID algorithms adapt quite well to any new hotend addition without manual tuning. So far Ive seen this is true and the hotend on my Mini+ heats up very rapidly, slightly overshooting and maintaining stability throughout the print.

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.

LIked the product except for the color. I would recommend the black one over the orange one. The orange came in a weird color, and it does not match the Prusa orange at all.

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.

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.
