I built these pieces to use with JAWong's 3D Catan Pieces ( http://www.thingiverse.com/thing:26979 ). They're scaled to fit in the holes and tracks inset in those pieces. Set is ready to print, once per player, in color or all in white/natural then paint or dye.

I've been printing at 10% infill, .27 layer height, 240 extruder and 120 bed. Sometimes the roads stick a little more than I'd like but 110 can leave the bottoms a little rough. Extruder rate of 80 can leave small gaps in the cones, but at an acceptable rate. They are easy to patch with modeling putty.
