The tabletop game Catan has many expansions, all of which come in the same box, which has a large plastic insert to organise the various tiles and playing pieces. this plastic insert wastes vast amount of space, to avoid either carrying 4 individual boxes if you wished to play 8 player expansions of the game i designed and created a new insert for the box that allows for the base game, the 7-8 player expansion, the Seafarers expansion and the 7-8 player Seafarers expansion to fit inside 1 of the origional boxes. It was made using a plywood outer shell (which could have a lid attached if you didnt wish to use the origional cardboard game box) with 3d printed internal plastic elements.
