Miracle Ball Stand

I have a pair of [Miracle Balls](https://www.amazon.com/Miracle-Ball-Method-Revised-Relieve/dp/1523510749), which help relieve back pain related to common issues. They tend to roll around when I'm not using them, so I made this stand for them.

There are two versions, one version accommodates a small book that came with the balls (at least the book I got when I bought them several years back). The other one is slightly smaller, as it doesn't need to store the book.

The balls themself are ~100mm in diameter, so this would work with any pair of ~100mm balls that you wanted a stand for.
