AstraMint 3D Printer Filament Spool Holder

Give your filament spool steady support and a feed path that stays clear of moving printer parts. The AstraMint Spool Holder comes in Single and Dual configurations, with axles, hub adapters, routing guides, and adjustable tensioning. • Fits 52–58 mm hubs and spools up to 220 mm across, up to 2.5 kg per position • Intended for PLA, PETG, ABS/ASA, and TPU with compatible printer settings • An anodized aluminum frame with a four-point M4/M5 mounting pattern Seat each spool evenly, align the holder with your frame or enclosure, and route filament toward the extruder without crossing a fan or gantry — in dual mode, keep the two lines apart. Set tension just enough to control slack while the spool still turns freely. A straighter path can cut avoidable drag, though print quality still depends on filament, extruder, and settings. For home benches, classroom labs, and maker spaces.
