This universal spool holder will hold any combination of 55mm wire and solder spools of most common widths. There are 20 wire feeds across, so you can pick whichever is closest to the center of the roll you're placing.

Fun facts:

• The spool holder has a standard 3x2 Gridfinity base, with 6x2mm magnet mounts.
• The model was made with Fusion360 and GridfinityGenerator.
• Inspired by benkrejci's Gridfinity Spool Holders.
• The Bambu Studio .3mf has a two-tone racing stripe setup. This makes the bin look faster. You can disable it by switching to one filament, or by removing the Filament Switches in the layer selector on the right after slicing.
