Lid indexes with the base using a 5mm diameter by 5mm magnet embedded in both sections. This is optional but does locate the 2 parts so the design flows from top to bottom.

Whilst the rainbow filament looks nice I think using a single colour holds the illusion of it being a giant ball of wool much better
