Safe Ring - for weightlifting, etc.

I needed a ring to wear doing weightlifting, pullups, crossfit, mechanical stuff, carpentry, etc. They sell "Safe Rings" that are made of rubber, but I figured this would be a great first test with NinjaFlex! I liked it so much I made one for my wife too.

I think I'm about a 10 for size and my wife is like a 7.5... I've included Autodesk 123D Design files... since your ring size probably doesn't match mine or my wife's!

There are probably better ones out there... but this was fun & quick
