3D Filament Reel Hub
thingiverse
This is a customizable hub for the ends of a 3D filament reel (print 2) that has a hole for a support rod, so it can work with numerous filament reel supports. You specify the outer hub radius, inner hub radius, which will set in the reel hole, and the radius of the support rod hole. An inner radius of 28mm should fit most 1kg reels. An inner radius of 16mm was sized to fit a .8kg reel from Sainsmart - I am unsure if all smaller reels have this same size hole or not. A "bolt_radius" of 4mm will allow a 1/4" bolt to fit.
