I love taking pics of minis from multiple angles, but the adjust-aim-shoot cycle gets tiring.
A cheap fidget spinner seems like a good start, but of course the center doesn't rotate --that's the point!
But if you have some reliably even hemispheres that you can put in the peripheral holes, you can raise a platform above the central bearing holder.
I used googly eyes for mine but there are other solutions. A 75mm or 3in base makes a good platform.
