Bigger capacity sample filament spool for small build plates

thingiverse

I designed my first spool assembly to fit snugly on a 120x120x120mm build plate, specifically my Monoprice Mini Select. My goal was also to have the option for a larger capacity spool that could hold multiple filament samples while keeping everything tidy and space-efficient. This larger capacity design still fits on the same size build plate if you print four arms in one print run and the hub separately. The internal diameter of the hub remains identical to its compact counterpart, ensuring compatibility with existing large spool holders from previous iterations. To accommodate various filament needs, I included arms designed to hold two, three, four, or five filaments each.
