Try our large format 3D printer spools which are perfect for long prints. Enjoy the same great filament in a new spool form factor. If you're tired of constantly swapping out smaller 1 kilogram or 200 gram spools, then this 5 kilogram spool is perfect. The large format spool will help reduce wasted filament at the end of the spool. You won't have to calculate if you'll have enough filament to finish a print.
