The bodies on the characters in this set were based on sine waves.  The intent was to create simple cute characters that were easily printable without support. Like my other sets this set is designed to be played, so while design elements are important, it is equally important that they are each distinctive enough in look to be easily recognizable. The pieces are also designed to be easily gripped between two fingers when playing. The king is a 1-3/4" base and is 4" tall. The set is fully printable without support.  The overhang on the knight's face is quite agressive so print the knight with .2mm layers for no drooping.  The other pieces should print fine with .3mm layers.  I used 28% infill to give the pieces some heft. Enjoy!
