A new development in the Idea to Reality blog post. While I was at Maker Faire in NY I got talking to a guy from 123D about the model I constructed using 123D Make. He suggested creating an Instructable on it. So I did, and here it is. If anyone is interested in how to create a prototype on the cheap. I go step by step into how to create your own prototype using 123D Make, some cardboard, and some glue.
