My motivation was pretty simple: every “spinning ring” I tried felt a bit fake.
They don’t actually spin — not like a real bearing.
So I wanted to see if I could make one that truly does.
At the end of the day it’s still just a ring. A small, minimal piece of jewelry.
But it happens to hide a tiny bearing that can hit around 800 RPM with a single flick.
That contrast is what makes it fun.
The way I think about it is this:
it’s like a normal-looking car that quietly turns out to fly.
Nothing loud or showy — until you decide to reveal what it can actually do.
If you’ve used a good fidget spinner for focus or stress, the feeling is similar.
This is basically that experience compressed into a silent, smooth, 2mm-thick ring you can wear without thinking about it.
The D20 idea grew out of that.
It’s not the main point — just a side effect of the spin being clean and consistent.
The reactions have been funny.
As a ring, some people say it’s “too plain.”
As a fidget spinner, it’s “not extreme enough.”
As a D20, it’s “not official enough.”
That’s what happens when something lands between categories.
To me it’s simply a pared-down version of all three.
If I wanted something louder, flashier, or more decorative, that’s easy to explore later.
This first version is about getting the core idea right:
a real, precise spin inside a clean 2mm ring.
Once that foundation works, the rest — styling, variants, whatever comes next — is straightforward.
Hope that gives a clearer sense of what I was trying to do.
