I created this pendant in ImplicitCAD using a Python script. I wanted to make a piece that would be castable and unique. This pendant is derived from the following parametric equation for a heart: X(t) = 16sin^3(t) Y(t) = 13cos(t) - 5cos(2t) - 2cos(3t) - cos(4*t) (Ref: http://stackoverflow.com/questions/8082429/plot-a-heart-in-r) I then wrote a recursive function in Python to generate a pattern of holes that seemed effervescent. I originally started this project with OpenSCAD (which is a fantastic program), however it proved difficult to create rounded edges. ImplicitCAD has a much simpler method for creating rounded edges. The language is similar to OpenSCAD, and I like the idea of scriptable CAD in general.This thing can be generated by running heart.escad in ImplicitCAD. heart.escad is generated by myHeart.py, which draws the polygon for the heart shape and creates the hole pattern. Of course, the finished STL file is also provided, which may be printed or cast.
