Dice Ring

I saw a very similar design (cast metal) somewhere and thought it was cool, so I decided to make my own version for 3D printing. It's neat because you can wear it like an ordinary ring and then take it off and roll it like a die. If it falls on its side that's a Zero :)

The default size has an internal diameter of 23mm which basically makes it a thumb ring for a big guy like me. The scaled down version which is 0.75 x has an 18mm inner diameter which is more like an ordinary ring.
