Rollup Dice Box - Tray inserts

Remix of 3D Printys design contest winning Rollup dice storage box to seperate the dice organisers from the tray itself, allowing for multicolour trays without the need for multi material printing or layor changes.

Parts are designed to press fit into the start middle or end plain trays (note only large square and hex have been tested but the small and circle versions should fit exactly the same)
