Introducing Boxfinity: Gridfinity for Filament Boxes. I wanted to create gridfinity for all the extra filament boxes I have that would make great storage for other items. Adding gridfinity to the box ensure that more sensitive items don't move around in the box when handling them on and off their storage shelf. I aspired to make it a fast print while maintaining integrity. I plan on adding different sizes for different manufacturer boxes, but starting with Bambu with Spool boxes.
