Filament Spool Mount For 8mm Frame

This thing mounts on the top of an 8mm 3D printer frame. It uses an 8mm threaded rod to hold the spool. In the slicer, I rotated the model 90 degrees about the y-axis for the right arm (which is the model given). For the left arm, I mirrored the STL in my slicer and rotated it 290 degrees about the y-axis so that I could use less support material and print the thing faster. I also used the Universal Filament Spool Holder to hold my spool on the 8mm threaded rod found here :http://www.thingiverse
