This is a screen cast of how I digitally designed "Clip on vase" using Rhnoceros 3D, Grasshopper and Waverbird. You can see full product presentation on my website ad-3d.com
few words about the product:
The “Clip on vase” is an accessory bringing double functionality to an IKEA Pokal glass, so that it can also be used as a vase. A simple click is required to convert your glass into an aesthetically pleasing vase.
The shape has been optimized so that it uses as little material as possible without compromising the functionality of the product. You can have a look at the product in details on my website: ad-3d.com
