Upgrade your cabinet with a filament feeder. This feeder will feed 4 spools simultaneously to your 3D printer. Use the excess space for storage for spools, not in operation. The spool rolls on 4 V-shaped rollers with closed Z bearings. Rollers are fully adjustable and will adapt to any spool width. Finally, four filament positioners are included for better guidance of filament. Filament, cabinets and printers displayed are not part of this purchase.
