As I never need the integrated filament stop on the spool body, I dropped it. When using MMU2, I rather rely on safely pulling the last centimeters of filament (w/o stopping it) for automatically switching to the next filament slot on the MMU2.
I used Prusament PET-G Orange and printed with 3 perimeters, 5% infill, w/o any support or brim.
For me, this master spool is the one and only. Perfect.
Many thanks for the original design and the remix as well!
