Lego-style Settlers of Catan

Build your game board!

Game tiles, borders, number tokens, resource and harbor markers, and player pieces are included. You may not need to print everything here, if you already own appropriate Lego pieces. 

Designed in OpenSCAD and MS 3D Builder.

SOURCES

This was first intended for Thingiverse, and made with help from the following items found there:

LEGO 2x2-Round For the number tiles and alternate resource markers.

Lego Tree For the trees, and as part of the sheep and wheat.

Customizable Lego-like Bricks Used to build the tiles and borders, and to make the Road, Settlement, and City pieces. Most of my renders for this project have an intentionally loose fit.

Regular Convex Polygon Generator Used to generate the initial hexagons for the tiles.

Lego Boulder  For the stone resource tiles.

Lego-like Minifig For the Robber. If you're going for a fully-printed game, this is the best option I've found.

Wooly Sheep Merged this with the base from the Lego Tree to make the sheep resource marker.

Catan Wheat Tile Merged this with the base from the Lego Tree to make the wheat resource marker.

PRINTING MANIFEST

2x2 Plate Connectors

There are 78 possible connections among tiles and borders for the standard base game. You do not need to print that many connectors. Six connectors holding the border together does a great job keeping the whole game secure.

Borders

Print 6 of these, preferably in blue. There are 2 options here. The border_with_base file includes a 1 or 2 layer (depending on resolution) flat section for the entire bottom. I found it difficult to get good bed adhesion for the regular border, and including this base layer was more effective than using a brim. However, this will add some extra post-print processing with a razor knife, so it's worth first seeing if you can print without the extra base.

I included cutouts for all the possible connection points, but it is not necessary to open up all of these. You can save a lot of time by only preparing the two at each end. Just a minute or so for both sides of each of the 78 possible connection points really adds up.

I had to place these diagonally on my 8" print bed to get them to fit. For smaller printers, or to work with some expansions, print 12 additional hex tiles.

Border Harbor Markers

Print 1 each for Sheep/Wool, Grain/Wheat, Wood/Lumber, Ore/Stone, and Brick. Additionally, print 4 of either the 3:1 Question or 3:1 Benchy. I have a set of each, and pick which one I want to use for a given game.

Hex Tiles

Print 19 of these. Do NOT generate supports. The supports you need are included as part of the piece; break them off on the edges when the piece finishes. As with the borders, a razor knife will be necessary to expose the Lego connector cutouts, but you can save a lot of time and skip that step.

For stacking the tiles vertically, I experienced a very tight fit at first. However, it quickly worked loose with use and fits much better now.

Circular Number Tokens

Print 1 Round2 tile, 1 Round12 tile, and 2 of each of the others. I recommend painting the top of the number, to help improve readability.

Road 4x1 Plate

Print 60(!) of these, 15 in four different colors. I had no trouble printing them in groups of 15, for each player color.

Settlement 1x1 Brick

Print 20 of these, 5 in four different colors. I print them in the same batch as the City pieces for each player color. 

City 2x1 Brick

Print 16 of these, 4 in four different colors. I print them in the same batch as the Settlement pieces for each player color. 

You can save some print time if you already have enough standard Lego pieces in any color for the City, Settlement or Road bricks.

Lego MiniFig

See the sources link. This is your Robber. I strongly recommend a real minifig.

Lego Tree

Print 4 of these, preferably in green, to mark your wood resource tiles. Find this in the sources section above. Alternatively, a few Lego pieces in green and brown can make a serviceable tree resource (see the pictures for examples).

Lego 2x2 Brick

Print 3 of these, preferably in red, to mark your brick resource tiles. This is something you might easily find in your Lego hoard.

Sheep

Print 4 of these, preferably in white, to mark your wool resource tiles.

Wheat

Print 4 of these, preferably in yellow, to mark your wheat/grain resource tiles. I found them very difficult to paint well, so you will save some work with a good original filament color.

Lego Boulder

Print 3 of these, preferably in gray, to mark your stone/ore resource tiles. Find this in the Sources section above. I found it difficult to get a good scale from the original file. Somewhere around 27% is correct, but I'm still not sure of the exact number. The pieces I have all needed work with a razor knife to fit properly.

For a flatter, easier to read game, print the rounded version of each resource and paint the embossed icon.
