I have been using THIS spool holder forever along with the AXLE that was designed for it. I have created and modified other brackets to accommodate them as well. So when I saw this, I knew my next project.

It turned out great and I hope you enjoy!!

UPDATE: I also removed the Creality branding on the filament guide and am attaching it as well. If you would rather have the original, you can find it with the design I remixed this from.
