A remix of rbuckbailey's harbor pieces designed for dualstrusion printers so you can get a nice crisp contrast between the background and its number, without painting. I recommend a blue bottom and colors to suit the material -- black for wild, red for brick, brown for wood, white for sheep, yellow for wheat, and grey for ore. Print as many as you need for either the 3-4 player game, or 5-6 player game. I've included the SketchUp files for further remixing. Note that the import process from rbuckbailey's stl makes a messy SketchUp file, and while I did some cleaning, they're still not as nice as if I had the original source (or had done it from scratch).Yes, all the "bottom" pieces look the same. Why the duplication? To make sure each bottom and its corresponding top line up perfectly when you merge them. I couldn't easily make sure all the tops were at the exact same starting coordinates, and ReplicatorG gives me no opportunity to align parts when merging (maybe other software does), so this is the surest way to get a good merge.
