This is a BB8 droid cookie cutter. It's 12cm in height, 6 mm deep, has 2 levels, each level is 1.5mm tall.
Also I've included SVG files, so you can extrude whatever size you need using Inkscape and Path2Cookie plugin Path2Cookie (http://www.thingiverse.com/thing:891647/).
I have extruded each layer into separate file and then combined them
