Yet another spool design, yet another spool support design. Thankfully, the new cardboard design allows for a minimal spool support. This one costs less than 16g (~8g each) of filament per spool. Printed with a 0.6mm nozzle at draft layer height. No supports required. The tabs keep it in place but is also removable for reuse.

The author marked this model as their own original creation.
