Fertility Rate in U.S. by Year
This is my first shot at taking existing data sets and turning them into physical objects. A colleague of mine gave me a basic line graph and I used Sketchup to turn it on it's side and do a 360 degree extrusion. Ends up looking a bit like a chess piece.
I didn't use any support material but you may want to include support due to the fairly large overhang near the bottom of the model. I printed this on a Replicator with the default settings.
