Modular Jewelry Display

I was looking for an earring display and was inspired by makebreakrepeat's design. However, I was disappointed that it didn't rotate, so I set about to fix that. In the process, I accidentally created a whole system of modular parts to make an infinite number of different displays. Oops. That's just the way I roll. I simplified a bit, as well, because my aesthetic sensibilities tend a bit more to the geometric. Most of this is a new build, but I did use the threads and the feet from the original design. It's more or less the same dimensions, and probably compatible.
