Filament Box Tabletop Inlay

Everbody of us knows the problem of numerous empty filament boxes. My old warhammer minis have only been stored in an unloveley big box with some cotton in it. 
So I came up with the idea to design a simple inlay to reuse my empty boxes.

The inlay holds up to 49 models with a 25mm round base. They snap into place.

The inlay is 210x210x2mm
