Refills

California Filament offers five of our most popular colors as refills. The filament comes neatly wound around a cardboard core, but without a spool. The cardboard core is compatible with Bambu Labs spools. There are many similar spool STL designs online. We've tested dozens and validated that the spools linked below work well with our refills.
