Spoolholder for 19-8-6mm Bearing/ 1kg 1.75mm Filament

I made this for my BQ filament rolls so it would fit perfect with my 19mm outer and 8mm inner diameter. This works perfekt for standart filament rolls with an inner diameter of 53cm.
Its made to be mounted on an 8mm rod.

So for this you need:

                              -19/8/6 Bearings
                              - 8mm Rod
                              - filament spool with around 53mm inner diameter
