Filament Spool Aid

This is a centre piece for a filament spool. It allows the spool to connect more efficiently to the central axis shaft and therefore less effort is required from the extruder motor.

This specific centre is removable, and its primarily designed for a Geeetech PLA spool reel and Geeetech axis shaft.

The diameter of the spool recomended is 57mm (maybe on other manufacturers spools)
The diameter of the holder central axis is 20mm (again maybe the same as other reprap)
