Filament spool spacers
thingiverse
I designed a custom spacer featuring a 20mm hole accommodating 2.1kg spools with a 57mm diameter opening, and measuring 60mm in width. Its purpose is to provide a snug fit for semi-loose applications, while an optional smaller spacer can be used to fill the remaining width gap on my MPSM setup, although it's not strictly necessary.
