Hi, I modified this to use as a mini extruder mount here: http://www.thingiverse.com/thi... but I am unsure how to 'credit' or link it correctly.
Works great! The design is sized just right, the 608 bearings fit snugly over the posts without rework and my spool is now rolling on it's own! I do need to print a filament holding arm next, as the filament rubs against my top frame rods when the Z axis is near the top (I added a sliced open straw to the threaded rod to make it slide around.)

Print two spool rollers and four bearing washers. Assemble as shown in the picture.
The parts were made in SolidWorks and repaired in Netfabb to ensure they are perfectly manifold
