Model based on a wooden chess set I bought in Salamanca (Spain) long ago. I was told it was made by a russian craftsman, the credit should go to him. On the other hand I introduced some minor changes when I thought they made sense.
In the gallery, there is a pic of the original wooden chess set. An old webpage I created about it:
The gallery also contains old renders of these pieces, in different materials: wood, glass, plastic. I created these in POV-Ray. The STL should correspond exactly to what you can see in these images.
