I made this terrain piece in basically the same design as JAWong like here http://www.thingiverse.com/thing:26979.
I was missing a water piece to complete my 3D catan game.
Hopefully you enjoy it, I also would like to know if you would change something on the piece.
2014-03-14 Edit: Added a new water tile without the iland. Its easy to print and gives more variation to the water areas of the game.
I printed the tile in light blue (water) and changed the color to yellow for the island and afterwards to white for the sign.
Changing the color is easily possible without having two nozzles. Just stop the print, move the head to a free space and change the filament. When pressing resume again, the print-head will move to the last position he was and continue printing.
