I present the Ring III, this model has been designed for printing in either Silver, Brass, Bronze, Gold, or Platinum if you're feeling adventurous, but as the pictures suggest; Bronze was the material I had in mind when designing it.
The sizing of this ring model is for a 23mm internal diameter, a UK Z+3 (US 14).
However it can be scaled up indefinitely and scaled down to have a 19mm internal diameter, a UK R1/2 (US 9).
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
