Book Ring for Large Thumbs

I printed one of these, only to discover that the thumb hole was uncomfortably tight and small for my thumb. Noticing that these thumb rings were typically made up of pretty basic shapes, I created a new one in Tinkercad designed specifically to comfortably fit my thumb. The interior diameter of the ring is 25mm.
