Autodesk recently launched a 123D Make! App for iPhones, so I used it to fabricate a vase, and then I laser cut it at TechShop SF.
The vase is great for holding some of the knick-knacks on my desk at the office!
Step 1: Download and Use the 123D Make App.
After you have downlaoded the 123D Make App to your iPhone, open it and begin using it. It will ask you to draw a shape, do so with your finger.
