The idea of a kinetic/twirling ring box is not mine; this execution of the idea is my original design. It's based on a mechanism that can be found in paper craft, paper engineering (pop up books), and origami. The idea is to convert linear motion into rotational motion. Almost all of these ring boxes I've seen use the same mechanism, which is a creased X type fold, with some ring-holder piece being affixed to the inside or convex side. Instead, to add some lifting action to the ring-holder, I affixed the ring-holder piece to the convex side of the X fold. Nothing earth shattering, but it did require more thought to the engineering of the housing since now I'd need a platform section and a hollowed out section that this ring holder could recess into.
The ones I've seen online seem overpriced for what they are (essentially a pop-up card piece of origami), I wanted to figure out a better way to do it.
I'm happy with the way it came out; it's slim, low profile, there are no visible mechanisms or hinges, it moves smoothly and reliably.
