Hatchbox filament spool holder with 608zz bearing

Just a quick and dirty spool holder I made for a spool of Hatchbox filament so it would feed smoothly into the printer. I wanted to make sure I did not get any banding from changes in filament feed tension. FreeCAD design file attached (created with v0.15). Just edit the "Inside of spool" radius if you want to use the same thing but on a spool with a different sized hole. Basically, all the sizes are labeled, so hopefully it should be easy to customize.
If you don't have FreeCAD, it is open so
