9/18/2025: Update the holder file with an adjusted mount angle. This should fix the incorrect orientation from version 3. I also uploaded the spool roller to this so that all the files are in one place. You will need two 608ZZ bearings for this to work properly. The mount has removable supports in the threads. Print vertically with the mount on the top for best results.

3/31/2025: Updated and uploaded new file without artifacts that caused open space and layers that were not joining.

Remixed design from https://www.thingiverse.com/thing:3209211 with the mounting to an Elegoo Centauri Carbon.
Combined the designed spool mount from https://makerworld.com/en/models/1147279-elegoo-centauri-carbon-spool-support
