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.)
