Has a slit in it so it can just slide over the rod for an easy install! Prints in TPU and fits well in the holes of the Bambu Lab rods at the bottom of the printer. Mainly to prevent plastic bits or screws when working on it from falling down in there lol I recommend a tiny bit of grease on the rod/inner hole of the print just to keep things smooth :)
Please note that you MUST remove these temporarily prior to a maximum height print or when lowering the bed all the way, otherwise the bed will lower into the cover. To be safe any print over 220mm I would take these out.
