Carcassonne Expansion Storage Boxes

One idea I have for storage boxes for Carcassonne. I found it is best to measure your specific tiles to get the box length since they seem to vary a bit in thickness--I add about 1.5 mm for fit. I started with a font posted on boardgamegeek.com (http://boardgamegeek.com/filepage/89695/carcassonne-icons-font) and converted the symbols I wanted to use into OpenSCAD
