Hinge Box

Dividers

Strips that split the inside of a box into compartments, locking together where they cross.

Across width: strips that run front to back. Across depth: strips that run left to right. 2 and 1 make six compartments.
Each strip is cut to the inside of the wall where it stands, so dividers in round and polygon boxes follow the wall too.
Where strips cross they lock with half-lap slots: front-to-back strips are slotted from the top, left-to-right ones from the bottom. Slide them together, then push the grid in.
Tabs on the bottom edge go into slots in the base. Over a support ring, the strip's ends step up onto the ring.
Height 0 makes them as tall as fits: just under a fixed lid, or under the lip of a removable one. Compartments narrower than 12 mm are left out.
