 Important: SVG produced by python script needs to be openend, transformed and saved in inkscape, otherwise import in CorelDraw fails
 
+In progress:
+- automate generation of plate segment
+
 TODO: 
 - stack 2 plates for better stability (add cuts at small circles)
 - second ring above the first plate to fix the containers and hide the gear mechanic (or manufacure them from acrylic to show the mechanic)
+- think about if stacked plate is to thick for a single gear (i.e. we may need two gears in order to transfer motion from below the plate to dispensers)
 - shovels for dispensers by cutting segments from a sphere
-- automate generation of plate segment
 - connectors for segments (jigsaw puzzle style)
