Inspired by similiar Catan tile holders, such as diw08's puzzle design, kingtut's derivation, and Tim Walsh's Hexels, the basic idea is to hold your existing tiles in these holders. These holders interconnect, creating a sturdy board, while also laying flat. With this design, it is easy to set up the board and play the game, rather than dealing with warped tiles popping up everywhere and game pieces that slide all over the board. The features of this design are: The 'T' interconnects Nooks for roads, ships, settlements, and cities to click into. Tiles may be easily removed by applying pressure to a corner. The OpenSCAD program is provided, so that you may tweak and modify all you want. I made these on a Printrbot LC v2, with numerous slic3r tweaks and a lot of cleanup with an exacto knife. Other printer setups may produce better prints.
