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

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.

No problems at all.

Saved my hotend from getting covered in PLA. Easy cheap upgrade to the prusa mini.

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

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.

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.

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.

Fits like a glove! This is perfect if you are looking to add a silicone sock to your heat block! I dont know if it really does anything for the heat block, but I will say it helps keep the small boogers off of it! Might also save you a severe burn if you touch it by accident.
