Spool holder for FLSUN Prusa I3

thingiverse

The spool holder prints perfectly fine on my trusty Ender 4. For newbies with their very first Flsun printer, a humble cardboard box can serve as a makeshift spool holder until you get your hands on this essential accessory. As it turns out, the kit doesn't come with a built-in spool holder, but don't worry - this handy tool works seamlessly with both small and large filament spools.
