Just another side mount spool holder. I printed with 5 perimeters and 9 layers at 0.2 for strength. This needs 3 M3 x 16mm flat head screws, as it mounts on the top right side to allow the filament to be loaded from the top.
Also, allowing faster filament changes (as when you want to change colors mid print).
The author marked this model as their own original creation.
