Summary

A 3D printable Settlers of Catan board with interlocking pieces.

Instructions

Print out one of each of the number discs
Print out 18 resource tiles: 3 Brick, 3 Rock, 4 Sheep, 4 Tree, and 4 Wheat (I used red, black, white, green, and yellow respectively)
Print out 9 Ports, 5 of the same colors as the 5 resources, and 4 others representing the 3 for 1 ports (I used blue)
Print out a desert (I tried to make it orange but it came out pink)

When printing out the tiles and the ports, make sure you print them in the same directions.

I printed the number discs with the number facing down to give it a smoother finish on top.

For the numbers I tried to use this: http://blog.makezine.com/2011/02/23/engraved-plastic-black-crayon-high-contrast-panels/ but it didn't really work. I ended up shaving off pieces of crayons, carefully placing them in the indents using tweezers, and then putting it in an oven to finish them. It's not a process I would recommend.
