About this 3D model

I tired to clean up the strainer of the kitchen sink every week, then I designed a disposable strainer printable. I choose OpenSCAD because it is highly parametric design. And fortunately, it made the design customizable to fit your sinks. 2014/6/15 update: I found that the knob for picking up was essential after use. So I added it referring http://www.thingiverse.com/thing:85416 . Set handle_height = 0 and handle_lower_diameter = 0 if no center knob is needed.
