Half Chess set thing. I built this with a very minimalist approach. Knights are scaled to Z 40mm, everything else is as-drafted. All bases are 25mm (slightly under 1 inch) designed for 1.5 inch square chess boards (12in. x 12in.). Will also fit on 1.25 inch square chess boards (10 in. x 10 in.) as is. Scale to fit.Chess set is ready to build. Rafting not necessary, supports required for King and Knight. High infill (50%) if you want them weighty, 10% infill if you want a really light object. Designed for bottom heaviness. Should take 1 inch felt pads or sticky magnets for ease of movement or metal boards.
