My take on Catan Polypanel style! The numbers are all triangle Polys with the number on top and the letter on bottom.   The way it works, you randomly put the order of the resources, then you put the triangles in order.  Start somewhere on the outside, start with A and then just swirl around until you run out.  After you have them in alphabetical order, flip them over.  You will notice i only printed one connector inside the triangle. When all three were printed it was impossible to put the triangle in. 

For all the resource pieces the base color should be the first 1.4-1.8 mm then you should pause the print and put on the second color.

For the numbers, have the first two layers with the first color, then pause, second color, after the 3 mm layer, third color.

I also included the raods.  I attempted the settlements and cities, but they did not work.  The road is perfect.
