Coasters? Wall decorations? Math swag? Ninja stars? You decide.

These models were made from Spirograph drawings using the new Shape Maker tool in the MakerBot PrintShop iPad app.

Step 1: Draw geeky math shapes with a Spirograph.

Step 2: From the PrintShop Shape Maker app on your iPad, take a picture of your drawing.

Step 3: Export and 3D print!

I resized all of the demo models to have 2mm height. But don't just print the demo models; go make your own!
