Spool hanger for closet wire rack

This is a spool holder that suspends a standard filament roll from a closet wire rack. Uses 2/ea M4x6x6 brass knurled nuts in the spool holder frame. Model should be able to be used with standard nuts and bolts instead of the brass inserts if so desired. Just add a set of washers between the spool holder frame and nuts to ensure proper fitment and strength is retained.
