This is a spool mount for the Elegoo Centauri Carbon that offers a different, raised location for the spool.  It uses one top-center side panel bolt to keep it from sliding and 4 12x6 N52 magnets to keep it firmly secured to the side panel.  There is options for using a spool with bearings that's perfect for things like TPU and a version without bearings that will work great with most everything else.  The version with bearings requires 2 15x24x5mm bearings.  Print the base in PETG as it won't droop over time, and the spool can be PLA, PETG, etc as it's fulled supported by the base.  Enjoy!
