Filament Spool Insert

This insert is made specifically for Real filament (made in Holland) spools. To lessen the friction between the cardboard spool and plastic spoolholder i made this.
Print it 2x, attach it to the spool and place the spool on the holder.

I included the file for Fusion 360, so you can remix it.
Printing time approx 2h40 each (first 4 layers @ 20mm/s, rest of print 40mm/s).
You can adjust infill and speed to reduce printing time, but these settings worked fine for me.

Enjoy!
