3D Printing Nerd's Essential Accessory: A Filament Spool Holder That Keeps Tension Under Control. Designed to prevent print head movement bounce from loosening filament on rolls, this simple yet effective holder allows smooth spinning of rolls without any issues. By utilizing 3D printed brackets and readily available 608 bearings used in skateboards and scooters, this solution ensures a secure fit for the spools. An 8mm shaft or a 5/16" rod, approximately 4.5" long, provides the perfect support for the bearing to move along the shelf without disrupting stored filaments.
