I present the Ring III, this model has been designed for printing in either: Brass, Bronze, Silver Gold, or Platinum if you're feeling adventurous, but Bronze was the material I had in mind when designing it.
The sizing of this ring model is for a 17.3mm internal diameter, a UK O (US 7).
The design can be scaled up indefinitely, but cannot be made in any smaller size.
If you would like a specific size then please send me a message or post the request below.
There are some more photos of this object and other examples of my work, both 3D printed and otherwise, on my 'Tofty' facebook page.
