Infinite time turner, inspired by the world of Harry potter.
Should be printed in materials that allow for detailed printing. Stainless steel, and other metals, will probably prevent it from moving. Silver is the only option in metal to allow moving parts. I printed this as a Test in WS&F and it looked mighty fine in my christmas tree. Currently working to make it pendant size. It's around 8cm wide, Will look great as a decorative piece, or a HUGE necklace.
