This has been a school challenge to create an accessory that had a logo on it, and I've the chance to make a statement ring of my personal brand. A slim version has been made recently, pictures below.
On the following year the challenge was to create some packaging for an item, and again, I chose the ring project: a box fit for its geometry and uniqueness. Oh, and it rocks.
Both items have been designed with Rhino3D and are currently 3D printed by Shapeways and sold also on Etsy and my personal online shop.
