These new flashforge printers come with their own standard spool sizes, meaning older filament spools you might already have could have a hard time fitting into the machines
We like the flashforge filaments, so we will include their range of filaments as well in the near future.
In the mean time, while you've still got some filament left, print out these spool holder adapters so you can fit your old filament to the new machines
We've found these on thingiverse, and haven't tested all of them, so feel free to experiment with what you can find on Thingiverse Website
