Filament Spool Two Piece

I designed this spool for an easy way to use filament left-overs. It is the same width as a standard 1kg spool and a little smaller in outer diameter. I made it this size so I would not have to re-adjust my spool holder to use left-overs.

I keep my left-overs measured and in baggies so they take up less room. These short filaments can then be placed on the hub side of the spool without having to wind it on and then the other side of the spool screws on like a cap.
