Harry Potter style Time Turner. You have the option of printing an immobile design in one piece or two. You can also print a mobile design. This was originally intended to be an ornament and so is only about 20mm across. It scales well to 200%. You may not get an intact print at 100% scale (see print settings). Most of the samples were printed using the rings without flanges. I added flanged rings but have only printed them using the mobile "print in place design"

I printed with a variety of filaments including petg, PLA, polysmooth, colorfab copper.
