i'm using eSun's PLA+ since i bought my X1C with AMS, sadly the new Spools come on cardboard and i dont trust it fully and dont want my AMS full of cardboard dust. eSun is offering a solution for this, so i thought i gonna share it.
Its two Rims that attach to the Sides of the Spool, each Rim weighs around 15g and the holes for the Filament are still free to use.
//EDIT 10/26/2023: Several people reported that the spolls wont fit their AMS after installing the Ring on the spool. it seems that Bambu has changed some Specs on newer AMS units. if you run into the problem that your Spools wont fit your AMS unit and the lid cant be closed DesignCraft hast uploaded a Lid Riser, so you can fit every Spool and still close your Lid
