Octave filament holder for the MakerBot Replicator

The one problem with the great series of MakerBot Replicator printers is that MakerBot markets filament (ABS, PLA, etc.) on reels with a center hole diameter of 2.06". I can't find any other company which uses reels of that size. The filament holders which come with the MakerBot printers are made to fit only that size hole. I've come to appreciate Octave brand filament. But Octave reels have a center hole size of 1.25". Because of this I've designed a holder to fit the Octave reels.
