smooth filament spool kit

uses 2 608 bearings and 3 inch 5/16 carriage bolt with 2 nuts. one clamps small round to existing bracket the other goes inside wing nut for easy spool change. made for overture paper board rolls. i created because tpu was kinking at feeder due to not rolling smooth on stock reel holder. pla worked great for me. bearings and nut fit tight so no glueing needed. supports needed
