Here are parts I've made to be used on JAWong's 3D Catan Pieces (http://www.thingiverse.com/thing:26979).
The parts are pretty detailed so you might have to print them somewhat slowly. When I designed these parts, I optimized them to print well on my Leapfrog Creatr at 0.25mm. Hopefully they'll come out well for your printers as well.
Be sure to check my other designs for more Catan parts!
Print slowly to keep the details
