In the Game of Thrones Chess set by Joe Lovchik from the 2014 CarveWrighht Conference the chess pieces are imported from thingiverse.com. When I import them using my STL importer they come over requiring wood with a 4.25" diameter. The pieces have only a 2" diameter base. Using a piece of wood 17/4 when only 8/4 is needed is a waste of wood and carving time. Is there a way that I can reduce the required carving piece to 2.25" or 2.5"? When I change the board diameter to 2.5" in the "Board Settings" the carved piece goes black and the piece to be carved vanishes. Thank you.
