Chess set built mostly of parabolas.
Designed using OpenSCAD with a generic parabola function that defines a polygon based on input width and height.
STL files are scaled in inches to print a pawn with a 1"x1" base and the pieces with a 1.25"x1.25" base.
One scad file lays out all of the pieces on a chess board. The other one is scaled and arranges the pieces onto a circular area for printing.
