I had made the mount because I didn't want to keep the spool on the side while I had the printer converted to direct drive. I found nothing else and the mount I did use before made me nervous about how to keep the spool.
Material - PLA
Infill - 10%
Supports - Yes
Hardware - 3 - M5x8 (the M5 screws that come with the handle maybe used, but it might not keep the mount snug.)
3 - M5 T-nuts
1 - M3x25 (you can use the screw that the mount comes with that attaches to the mount on the side of the printer. I use a T-nut to keep it secure.
