Settlers of Catan Costs Water Tile - Multicolor

I really liked the idea of putting all of the building cost information on an almost useless empty water tile, so I made this variation that will fit my own custom Magnetic Base (http://www.thingiverse.com/thing:1853267).

I wanted each symbol to be properly colored, but I did not want to do any painting. To this end, I've slightly modified the symbols so I can change the filament color at specific layer heights so each symbol will result with the color I want.
