Open Beam Compatible Filament Spool Holder

I really like the original MakerBot Filament Spool holder, and most of the new spool holders for the kossel can't be printed on a 4" square platform. I decided to modify the Makerbot Filament Spool holder to make it compatible with open beam. To get started, I used 3 shells and 30% infill, but I'm sure someone else could achieve better results. Mine didn't turn out perfectly, but that's okay. I added a lot of ears on the part to prevent curling, because this particular part is one of the worst cases for causing curl. The gap in the design is a tapered slot, which causes it to become clamped to the open beam when the fasteners are tightened. You will need M3 nuts and M3x 8mm fasteners to complete the project.
