C-beam Dual Spool Holder

thingiverse

This is a versatile spool holder that securely attaches to the C-Beam frame, specifically designed to accommodate standard 50mm+ ID spools and can even handle up to 150mm wide ones at once, typically holding two spools simultaneously in most scenarios. No bearings were integrated into its design; instead, the friction created by the holder itself provides the necessary counter torque to prevent unwinding of the spool during 3D printing operations, thereby minimizing tangled filament issues.
