Snap-Together "Master Spool" for Loose Filament (eSun Refillament)

thingiverse

A game-changing snap-together spool for eSun's "Refillament" just hit the market. It's frustrating that every time you buy filament, you're stuck with this non-recyclable polystyrene spool that has to be tossed in the trash and sent off to a landfill. Repurposing them as storage containers or wheels is initially charming, but eventually, the ever-growing stack of empty black husks starts to take its toll. I've successfully printed multiple rolls of eSun's loose PLA on this spool without any issues. It spins smoothly, doesn't get caught, and the small holes make it easy to store the filament when not in use. You'll need 2 disks and 3 snap hooks to assemble it. Print at 100% infill because everything is essentially flat. I've also included the Fusion 360 file if you want to resize it for your preferred filament. Note: The "download all files" option is broken, so download the files individually, please.
