Writing for The Economist, Glenn Fleishman has a fascinating look at the design and prototyping process of Glif, an iPhone 4 tripod adapter that just raised $70,000 in two days on Kickstarter:
They started with a computer model of the adapter, created with Rhinoceros 3D design software. The software is $995 for Windows, but they used the beta test version for Mac OS X, which is free. They tested their designs through rapid prototyping, uploading files to Shapeways in the Netherlands. It took about ten days for Shapeways to “print” each prototype in 3D, and a day later it would be in the designers’ hands in New York. Shapeway charges by material volume, so each each Glif test cost about $10. They would try out a few variants each time just to meet a $25 minimum.
