Filament Spool mount

Since buying the K1Max I needed a new filament spool holder as the rear mount on the machine is totally useless.
I liked the spool holder I'd been using on my Ender 3V2

So just needed a new mount for that so I designed this on Fusion 360 and printed two of them so I can load a second spool ready for a quick change over of colours or just a backup spool if running low ready to change over.
