These are the standard Working Tools for a Freemason. There is about .017 (+/-.005) inches of material shrinking when printing in metal. This is why you will hear other designers recommend getting one size larger. I accounted for this shrinking in my design so that the resulting ring will be the right Ring Size. Note - this ring is narrow at .about 2 Inches wide.
I purchased this in Stainless Steel first to get an understanding of the form and fit of 3D Printed Ring. Although it looks amazing and has this antique look to it, the Ring browned my skin at first and later cleared itself up. Because of this, I recommend getting Silver or Gold Solid or Plated Brass.
A few masons have asked for this ring in a cheaper material to verify their ring size. I included Metallic Plasitc for this purpose. I don't recommend getting this material as your permanent choice.

This Ring was designed by me, Darren Hartenstine. If you're curious why a Masonic Ring in my mix of Products - well, I'm a Freemason and wanted a ring that embodied my ambition and drive in becoming a better man. In the spirit of masonry, how better than designing it myself using the tools of modern times. This Ring is actually what started my journey into Shapeways and was the first of all of the Products located in my shop.
