triple color spool

thingiverse

The heavy-duty spool impressed me, as an entire color vanished swiftly. Laziness prevented changing filaments; thus, I redesigned the part for multiple colors and materials. Now, it features three slots. Secure first filament via 3mm arm holes, carefully wind each slot without straining the spool. Avoid using filament wound on smaller spools, as it puts excessive force on the arms.
