3D Catan Ocean Border with Snaps

I designed these border pieces to work with JAWong's 3D Catan Pieces (http://www.thingiverse.com/thing:26979).

The parts are designed to have a little clearance in the dovetail so errors in one won't transfer to the next piece. If yours come out too tight, you may need to lower your flowrate multiplier or lightly sand the interfering faces.

Since I planned to use this with the seafarers expansion where the port position varies a lot, I decided not to make the depression for the ports.
