vector (cdr) file for cutting 2D chess pieces with any cutting machine.
There are only one contour for each chess piece of both colors, so you should multiply them to have:
and 16 stands
of each color.
Moreover, you should transform attaching slots (on stands) and attaching lugs (on chess pieces) to match each other and using material. For example, I used 3mm thick plexiglass, so lugs were 3mm high and slots were 3mm wide.
I've made my Ñhess sets by laser cutting machine in Moscow FabLab (http://fablab77.ru)
